For example, Telnet and FTP sessions must be re-established and VPN tunnels must be renegotiated. A Cluster Node can also be a single firewall, allowing an Active/Active cluster setup to be built using two firewalls. Virtual Group Link Weight of the Cluster Nodes This is the number of interfaces in the Virtual Group that are up and have a configured virtual IP address. Do you have any VLAN's configured on the WAN switch? The failing service is isolated as early as possible, and the failover mechanism repairs it automatically. . Certain packet flows on the active unit are selected and offloaded to the standby unit on the Active/Active DPI Interface. 10. SonicWall NSa 2650 High Availability. This section describes the requirements for registering your Dell SonicWALL network security appliance and licensing the SonicWALL High Availability features. The Secondary SonicWALL maintains a real-time mirrored configuration of the Primary SonicWALL via an Ethernet link between the designated HA ports of the appliances. Navigate to the left menu. SonicWALL NSA 3500 in HA setup with BGP for ISP automatic failover. The standby firewall in an HA pair is lightly loaded and has resources available for taking over the necessary processing, although it may already be handling DPI traffic if Active/Active DPI is enabled. Select the primary and secondary management uplink as 1. For example, a redundant switch might be deployed on the WAN side if traffic passing through it is business-critical. Active/Active Clustering Full Mesh configuration is an enhancement to the Active/Active Clustering configuration option and provides the highest level of availability possible with high performance. Physically connect the designated HA ports from the Primary to the Secondary HA unit. Failover - Describes the actual process in which the Standby unit assumes the Active role following a qualified failure of the Active unit. In this configuration with PortShield functionality in HA mode, firewall interfaces that serve as PortShield hosts should be connected to the switch on active and standby units. AD, DFS, RRAS, IIS, WSUS, WDS, Storage Server management about High Availability. When a redundant switch is configured, SonicWALL recommends using a redundant port to connect to it. The Secondary now has all of the users session information. Click CONFIGURE RADIUS on the right. In case of a failover, the following sequence of events occurs: 1. Cisco, HP and Sonicwall networking equipment. When a Cluster Node is a Stateful HA pair, Active/Active DPI can be enabled within the Cluster Node for higher performance. For example, every SonicWALL firewall uses redundant ports to connect twice to each networking device. I am going to use Sonicwall NSa 4650 Firewall. When physical interface monitoring is enabled, with or without logical monitoring enabled, HA failover takes precedence over Active/Active failover. Status should look as below under Monitor | High Availability Status. By submitting this form, you agree to our Terms of Use and acknowledge our Privacy Statement. 15. Note When Active/Active Clustering is enabled, the SonicOS internal DHCP server is turned off. When more than two Cluster Nodes are configured in a cluster, these factors determine the Cluster Node that is best able to take ownership of the Virtual Group. If a second interface is physically connected, configure it as the Active/Active DPI Interface 2 for Active/Active DPI. 5. It features both inbuilt and an expandable storage of up to 256GB, that enables various features including logging, reporting, caching, firmware backup and more. A Virtual Group is a collection of virtual IP addresses for all the configured interfaces in the cluster configuration (unused/unassigned interfaces do not have virtual IP addresses). But it's good to hear that it works for others in Gen 6 with a fail over time of 1-2 min. Because the appliances are using the same IP address, when a failover occurs, it breaks the mapping between the IP address and MAC address in the ARP cache of all clients and network resources. During normal operation, the Primary SonicWALL is in an Active state and the Secondary SonicWALL in an Standby state. On the Network > DHCP Server page, disable the DHCP server and delete all DHCP server lease scopes. Select the primary and secondary management uplink as 21. ), it immediately informs the Secondary appliance. The NSa 4700 has been built from the ground up with the latest hardware components, all designed to deliver multi-gigabit threat prevention throughput " even for encrypted traffic. Faster failover performance - By maintaining continuous synchronization between the Primary and Secondary appliances, Stateful Synchronization enables the Secondary appliance to take over in case of a failure with virtually no down time or loss of network connections. To sign in, use your existing MySonicWall account. Expand Users and select Settings. In the event of the failure of the Primary SonicWALL, the Secondary SonicWALL takes over to secure a reliable connection between the protected network and the Internet. Do you also have a switch between ISP modem and SonicWALL's? Dynamic WAN clients (L2TP, PPPoE, and PPTP), Deep Packet Inspection (GAV, IPS, and Anti Spyware), IPHelper bindings (such as NetBIOS and DHCP), Dynamic ARP entries and ARP cache timeouts. When Active/Active Clustering is initially enabled, the existing IP addresses for all configured interfaces are automatically converted to virtual IP addresses for Virtual Group 1. SonicWall NSA Series - High Availability. Designed for mid-sized organizations and distributed enterprise with SD-Branch locations, the TZ670 delivers industry-validated security effectiveness with best-in-class price-performance. Create a full mesh configuration of NAT rules in the cluster so every interface-pair has a NAT rule which replaces the source IP address in the packet with the virtual IP of the egress interface. Configure and maintain the VPN and remote site connectivity. This Virtual Group functionality supports a multiple gateway model with redundancy. Currently working as a Resident Engineer at MOMRAH: - Perform full assessment for the PANW Panorama and NGFW deployment design and configuration. Fyi, I am using stateful HA (Gen6) with 2 PPPoE interface and its working fine & the fail-over happening in 1-2min. Note Before performing the procedures described in this section, ensure that you have completed the prerequisites described in Active/Standby and Active/Active DPI HA Prerequisites. The Secondary appliance must issue an ARP request, announcing the new MAC address/IP address pair. Configure Virtual Group IP addresses on the Network > Interfaces page. SVRRP is used to communicate Virtual Group link status and ownership status to all Cluster Nodes in the cluster. To set up HA with two switch management ports, Configuring HA and PortShield With a Common Uplink. Has any one experience with a situation like this? The SonicWall TZ670 is a desktop-form-factor next-generation firewall (NGFW) with 10 Gigabit Ethernet interfaces. 4. To enable link detection between the designated HA interfaces on the Primary and Backup units, leave the Enable Physical . This other switch avoids the looping of packets for the same PortShield VLAN. The Primary and Secondary IP addresses configured on the High Availability > Monitoring page can be configured on LAN or WAN interfaces, and are used for multiple purposes: As independent management addresses for each unit, regardless of the Active or Standby status of the unit (supported on all physical interfaces), To allow synchronization of licenses between the standby unit and the SonicWALL licensing server, As the source IP addresses for the probe pings sent out during logical monitoring. 8. Optionally, for port redundancy for Active/Active DPI ports, physically connect a second interface between the two appliances in each HA pair. 2. Two appliances configured in this way are also known as a High Availability Pair (HA Pair). The Secondary appliance begins to send gratuitous ARP messages to the LAN and WAN switches using the same Virtual MAC address and IP address as the Primary appliance. The Gen 7 TZ series are highly scalable, with high port density of up to 10 ports. Active/Standby HA provides the following benefits: Increased network reliability In a High Availability configuration, the Secondary appliance assumes all network responsibilities when the Primary unit fails, ensuring a reliable connection between the protected network and the Internet. Select the primary management uplink and primary switch uplink as 1. This section contains the following subsections: How Does Stateful Synchronization Work? 12. High Availability (HA) allows two identical firewalls running SonicOS to be configured to provide a reliable, continuous connection to the public Internet. Cluster Node management and monitoring state messages are sent using SVRRP over the HA port connection. Redundancy is achieved at several levels with Active/Active Clustering: The cluster provides redundant Cluster Nodes, each of which can handle the traffic flows of any other Cluster Node, if a failure occurs. Just try to figure out if there's a problem in the setup. HIGH AVAILABILITY NETWORK . The maximum number of Cluster Nodes in a cluster is currently limited to four. It is an active-standby configuration where the Primary appliance handles all traffic. 4. Select the firewall uplink as Interface X3. Active/Active failover is stateless, meaning that network connections are reset and VPN tunnels must be renegotiated. When the Active/Active Clustering configuration is applied, up to three additional Virtual Groups are created, corresponding to the additional Cluster Nodes added, but virtual IP addresses are not created for these Virtual Groups. The power is unplugged from the Primary appliance and it goes down. A Virtual Group is only owned by one Cluster Node at a time, and that node becomes the owner of all the virtual IP addresses associated with that Virtual Group. The High Availability pair uses the same LAN and WAN IP addressesregardless of which appliance is currently Active. This KB explains how SonicWall switches can be deployed with the SonicWall UTM devices in high availability mode.The switches can be deployed with one or two dedicated uplinks and also with common uplinks. The diagnostics check internal system status, system process status, and network connectivity. SVRRP is also used to synchronize configuration changes, firmware updates, and signature updates from the Master Node to all nodes in the cluster. Physically connect the LAN and WAN ports of all units to the appropriate switches. The link is sensed at the physical layer to determine link viability. When upgrading to SonicOS from a previous release that did not support Active/Active Clustering, it is highly recommended that you disable High Availability before exporting the preferences from an HA pair running a previous version of SonicOS. BGP is supported in clusters, and will also appear as parallel BGP routers using the virtual IP address of the Cluster Nodes interface. Active/Active Clustering Full-Mesh Overview, Verifying Active/Active Clustering Configuration, Configuring VPN and NAT with Active/Active Clustering, Configuring Active/Active Clustering Full Mesh, Configuring Network DHCP and Interface Settings, Registering and Associating Appliances on MySonicWALL. Add to Cart. This chapter contains the following main . A Full Mesh deployment uses redundant ports on each of the main traffic ports (LAN, WAN, etc. In the case of failure of the HA port connection, SVRRP heartbeat messages are sent on the X0 interface. Before you can enable Active/Active Clustering, Stateful Synchronization, and Active/Active DPI, these features must be licensed. All Cluster Nodes share the same configuration, which is synchronized by the Master Node. After logging into the Master Node, monitoring configuration needs to be added on a per Node basis from the High Availability > Monitoring page. The Standby identifier is a logical role that can be assumed by either a Primary or Secondary hardware unit. The PortShield members should also be connected to ports on the switch. In a larger deployment, if Cluster Node 1 owns three or four Virtual Groups, traffic is distributed among the redundant ports traffic for Virtual Groups 1 & 3 is sent on X3, while traffic for Virtual Groups 2 & 4 is sent on X4. Port redundancy, in which an unused port is assigned as a secondary to another port, provides protection at the interface level without requiring failover to another firewall or node. The owner of Virtual Group 1 is designated as the Master Node. Click Manage in the top navigation menu. There are two types of failover that can occur when Active/Active Clustering is enabled: High Availability failover Within an HA pair, the Secondary unit takes over for the Primary. High Availability. Note For interfaces with configured virtual IP addresses, Active/Active physical monitoring is implicit and is used to calculate the Virtual Group Link Weight. When the PC user attempts to access a Web page, the Secondary appliance has all of the users session information and is able to continue the users session without interruption. Configure the Load balancing rules to access the internal Virtual Machines from the public network. In each Cluster Node, only the active unit processes the SVRRP messages. Active/Active DPI can be enabled, providing increased throughput within each Cluster Node. The section About Failover provides more information about how failover works. But, if one SonicWALL can ping the target but the other SonicWALL cannot, the HA pair will failover to the SonicWALL that can ping the target. And the HA deployment I usually see in enterprise: Two firewall, two switches stacked using LACP providing no single point of failure. We had to wait around 10 minutes before the secondary unit had a ping reply at the WAN IP address. Featuring a high port density (including 16 x 1GbE ports and three x 10 GbE ports), the solution supports network and hardware redundancy with high . Configuring HA Using Two Switch Management Ports, ICMP Ping Latency with SonicWall switches, How to enable/configure SNMP on sonicwall switches. In the event of the failure of the Primary SonicWALL, the Backup SonicWALL takes over to . If the firmware configuration becomes corrupted on the Primary SonicWALL, the Secondary SonicWALL automatically refreshes the Primary SonicWALL with the last-known-good copy of the configuration preferences. See the following sections for descriptions of these new concepts and changes to existing functionality: About Redundant Ports and Redundant Switches. 13. In case of a fault condition on one of the firewalls in this deployment, the failover is not stateful since neither firewall in the Cluster Node has an HA Secondary. 3. Cluster Node management and monitoring state messages are sent using SVRRP. You can unsubscribe at any time from the Preference Center. When enabled, OSPF runs on the OSPF-enabled interfaces of each active Cluster Node. Any network appliance that performs deep packet inspection or stateful firewall activity must see all packets associated with a packet flow. Installed high availability Big IP F5 LTM and GTM load balancers to provide uninterrupted service to customers. This provides load sharing. Stateful HA is not required, but is highly recommended for best performance during failover. Configure settings in the High Availability > Advanced page. Dynamic state synchronization is only available in a Cluster Node if it is a Stateful HA pair. Preempt - Applies to a post-failover condition in which the Primary unit has failed, and the Secondary unit has assumed the Active role. -Deploy, upgrade, review, and document network infrastructure, including high availability firewalls and stacked switching; Install and configure Windows Servers, peripherals, network devices and storage devices in accordance with internal standards and project requirements. In the backup SonicWall text box, enter the backup firewall's serial number as shown on the bottom (or back) of the backup unit, then click apply. When both High Availability failover and Active/Active failover are possible, HA failover is given precedence over Active/Active failover for the following reasons: HA failover can be stateful, whereas Active/Active failover is stateless. Additional NAT policies can be configured as needed and can be made specific to a Virtual Group if desired. The Primary identifier is a manual designation, and is not subject to conditional changes. The documentation of SonicWALL (G6 and G7 says that stateful should be disabled), but of course this is very useful information. Stateful Synchronization is not load-balancing. This eliminates the possibility of configuration errors and ensures the uniqueness of the Virtual MAC address, which prevents possible conflicts. Minimal impact on CPU performance - Typically less than 1% usage. SonicWall NSa 3650 High Availability. Sonicwall VPN solution provides our employees with secure access to internal and external data and resources. Upon failure of the Primary unit, the Secondary unit will assume the Active role. The virtual MAC address is created in the format 00-17-c5-6a-XX-YY, where XX is the interface number such as 03 for port X3, and YY is the internal group number such as 00 for Virtual Group 1, or 01 for Virtual Group 2. This section describes the current limitations and special requirements for Active/Active Clustering configurations with regard to routing topology and routing protocols. Start up the other units in the Active/Active cluster. For communication between Cluster Nodes in an Active/Active cluster, a new protocol called SonicWALL Virtual Router Redundancy Protocol (SVRRP) is used. All devices in the Cluster must be of same product model and be running the same firmware version. A virtual MAC address is associated with each virtual IP address on an interface and is generated automatically by Sonic OS. As part of the configuration for Active/Active Clustering, the serial numbers of other firewalls in the cluster are entered into the SonicOS management interface, and a ranking number for the standby order is assigned to each. Don't know if the sysadmin of that company have done that, but maybe useful to know. Configuring Active/Active DPI High Availability. If Stateful HA is enabled for the pair, the failover occurs without interruption to network connections. Add to Cart. Navigate to High Availability | Settings. Active/Active Clustering configuration can include configuring Virtual Group IDs and redundant ports. Note All Cluster Nodes in the Active/Active cluster share the same configuration. In general, any network advertised by one node will be advertised by all other nodes. HA requires one SonicWALL device configured as the Primary SonicWALL, and an identical SonicWALL device configured as the Secondary SonicWALL. If the timestamps are out of sync and the Standby unit is available, a complete synchronization is pushed to the Standby unit. Typically this is handled by another device downstream (closer to the LAN devices) from the Active/Active Cluster, such as a DHCP server or a router. You need to configure these virtual IP addresses on the Network > Interfaces page. 6. For physical connectivity, the designated HA ports of all the units in the cluster must be connected to the same Layer 2 network. Virtual Group 1 traffic is sent on X3, while Virtual Group 2 traffic is sent on X4. For larger deployments, the cluster can include eight firewalls, configured as four Cluster Nodes (or HA pairs). #01-SSC-2007. Cost-effectiveness High Availability is a cost-effective option for deployments that provide high availability by using redundant SuperMassives. This greatly simplifies the failover process as only the connected switches need to update their learning tables. The Cluster Node consists of a Stateful HA pair, in which the Secondary firewall can assume the duties of the Primary unit in case of failure. Start up the other units in the Active/Active cluster. Todays routers do attempt to forward packets with a consistent next-hop for each packet flow, but this applies only to packets forwarded in one direction. Yes. All other network devices continue to use the same virtual MAC addresses and do not need to update their ARP tables, because the mapping between the virtual IP addresses and virtual MAC addresses is not broken. Note When HA Monitoring/Management IP addresses are configured only on WAN interfaces, they need to be configured on all the WAN interfaces for which a Virtual IP address has been configured. Configuration changes and firmware updates are only allowed on the Master Node, which uses SVRRP to synchronize the configuration and firmware to all the nodes in the cluster. HA monitoring can be configured for both physical/link monitoring and logical/probe monitoring. All rights Reserved. This is in contrast to traditional IP routing in which each packet in a flow may technically be forwarded along a different path as long as it arrives at its intended destination the intervening routers do not have to see every packet. One of the most common methods of deployment is the Active\Standby deployment, however, it can be configured in Active\Passive, Active\Active DPI and Active\Active Cluster type deployments as well. Virtual MAC for reduced convergence time after failover The Virtual MAC address setting allows the HA Pair to share the same MAC address, which dramatically reduces convergence time following a failover. In case of a failover, GMS administration continues seamlessly, and GMS administrators currently logged into the appliance will not be logged out, however Get and Post commands may result in a timeout with no reply returned. The Master Node is also responsible for synchronizing firmware to the other nodes in the cluster. Update network diagram: SuperMassive network diagram. ), and uses redundant upstream routers in addition to redundant switches. Select the primary and secondary management uplink as 1. Currently, daisy chain switch mode is not supported. Start up the other units in the Active/Standby HA pair. Resolution. Select the firewall uplink as Interface X0. - Provide and apply the recommended Firewalls design changes for enhancing performance, availability and provide more restriction on the . 17. The following features are not supported when Active/Active Clustering is enabled: The following features are only supported on Virtual Group 1: The Active/Active Clustering feature is not backward compatible. The secure connection is pretty fast and reliable and keeps our data end to end encrypted. I am a little bit confused that stateful works in your situation. To configure High Availability on the Primary SonicWall, perform the following steps: Login to the SonicWall management Interface. Click on Add. Standby - Describes the passive condition of a hardware unit. Of these, two have configurable settings that pertain to Active/Active Clustering, one displays status for both the cluster and the HA pair to which you are logged in, and one pertains only to configuration for the local HA pair. You can view these NAT policies in the Network > NAT Policies page. 7. If both cannot successfully ping the target, no failover occurs, as the SonicWALLs will assume that the problem is with the target, and not the SonicWALLs. It is up to the network administrator to determine how the traffic is allocated to each gateway. 2. The following sections describe how to prepare, configure, and verify HA and Active/Active Clustering: Active/Standby and Active/Active DPI HA Prerequisites, Configuring Active/Active Clustering and HA, Verifying Active/Active Clustering Configuration, Configuring VPN and NAT with Active/Active Clustering, Configuring Active/Active Clustering Full Mesh. Active/Active failover transfers ownership of a Virtual Group from one Cluster Node to another. The latter is the High Availability > Monitoring page. CAUTION:Load Balancer uses a distributed probing service for its internal health model. Even if the standby unit was already registered on MySonicWALL before creating the HA association, you must use the link on the System > Licenses page to connect to the SonicWALL server while accessing the Secondary appliance through its management IP address. The benefits of Active/Active Clustering include the following: All the firewalls in the cluster are utilized to derive maximum throughput, Can run in conjunction with Active/Active DPI to perform concurrent processing of IPS, GAV, Anti-Spyware, and App Rules services, which are the most processor intensive, on the standby firewall in each HA pair while the active firewall performs other processing, Load sharing is supported by allowing the assignment of particular traffic flows to each node in the cluster, All nodes in the cluster provide redundancy for the other nodes, handling traffic as needed if other nodes go down, Interface redundancy provides secondary for traffic flow without requiring failover, Both Full Mesh and non-Full Mesh deployments are supported. Fill in all necessary information like Serial number, IP address, username, password. . Copyright 2022 SonicWall. You can unsubscribe at any time from the Preference Center. As with OSPF and RIP, configuration changes made on the Master node will be applied to all other Cluster Nodes. Physically connect an additional interface between the two appliances in each HA pair if you plan to enable Active/Active DPI. If each Cluster Node is an HA pair, the cluster will include eight firewalls. By submitting this form, you agree to our Terms of Use and acknowledge our Privacy Statement. You can use the following name servers to point websites too; au- dns .f2hcloud.com | 139.99.135.201 - Australia. 6. I do have switch in between Firewall & ISP Modem. The Cluster Node that becomes the Virtual Group owner also becomes the owner of all the virtual IP addresses associated with the Virtual Group and starts using the corresponding virtual MAC addresses. Every device is wired twice to the connected devices, so that no single point of failure exists in the entire network. How Does Active/Active Clustering Work? 22. 14. 13. 11. For increased performance in an Active/Active cluster, enabling Active/Active DPI is recommended, as it utilizes the standby firewall in the HA pair for Deep Packet Inspection (DPI) processing. This field is for validation purposes and should be left unchanged. Routers make no attempt to direct return traffic to the originating router. 2022 - 9 . Please can anyone provide step-by-step tutorial for configuring a high availability cluster (active-standby) with two Sonicwall 4650 firewalls. 9. 3. Create a User. Primary - Describes the principal hardware unit itself. NOTE: The above configuration will deploy NSv_Azure_HA1, NSv_Azure_HA2 along with external Load balancer NSv_Azure_HA-ELB and internal Load balancer NSv_Azure_HA-ILB. Enter the Cluster Node owner/standby rankings for each Virtual Group. Note that non-management traffic is ignored if it is sent to one of the monitoring IP addresses. There are several important concepts that are introduced for Active/Active Clustering. Physical monitoring cannot be disabled for these interfaces. This section provides an introduction to the Stateful Synchronization feature. 19. The SonicWall is the high performing, secure Unified Threat Management (UTM) firewall. When using logical monitoring, the HA pair will ping the specified Logical Probe IP address target from the Primary as well as from the Secondary SonicWALL. All configuration changes are performed on the Primary appliance and automatically propagated to the Secondary appliance. Preform the tasks described in Active/Standby and Active/Active DPI HA Prerequisites, including registering and associating the appliances on MySonicWALL and licensing the high availability features. For example, in a 4-node cluster, if the router-ID 10.0.0.1 was configured on the Master node, the router-IDs assigned would be as follows: RIP is supported, and like OSPF, will run on the RIP-enabled interfaces of each Cluster Node. No routing updates are necessary for downstream or upstream network devices. An optional second power supply provides added redundancy in case of failure on select models. When using SonicWALL Global Management System (GMS) to manage the appliances, GMS logs into the shared WAN IP address. Enter the serial numbers of other units in the Active/Active cluster. Figure 50:13 Active/Active Clustering Topology. To configure High Availability on the Primary SonicWall, perform the following steps: Login to the SonicWall Management Interface. Note The Active/Active virtual MAC address is different from the High Availability virtual MAC address. Minimal impact on bandwidth - Transmission of synchronization data is throttled so as not interfere with other data. When Active/Active Clustering is enabled for the first time, the configured IP addresses for the interfaces on that firewall are converted to virtual IP addresses for Virtual Group 1. Navigate to SonicWall NSv Azure Template using your Microsoft Azure Account. Resolution. A WAN interface failure can trigger either a WLB failover, an HA pair failover, or an Active/Active failover to another Cluster Node, depending on the following: WAN goes down logically due to WLB probe failure WLB failover, Physical WAN goes down while Physical Monitoring is enabled HA pair failover, Physical WAN goes down while Physical Monitoring is not enabled Active/Active failover, Routing Topology and Protocol Compatibility. 5. In a deployment with two Cluster Nodes, the X0 Virtual Group 1 IP address can be one gateway and the X0 Virtual Group 2 IP address can be another gateway. NAT policies are automatically created for the affected interface objects of each Virtual Group. From a routing perspective, all Cluster Nodes will appear as parallel routers with the virtual IP address of the Cluster Nodes interface. As the Primary appliance creates and updates network connection information (VPN tunnels, active users, connection cache entries, etc. Created and supported private cloud using Exchange 2010, Windows Server 2008 and RemoteApp publishing. Configure per-unit IP addresses in the High Availability > Monitoring page. Afterwards, switch to the Authentication tab. In a typical configuration, each Cluster Node owns a Virtual Group, and therefore processes traffic corresponding to one Virtual Group. Feature Support Information with Active/Active Clustering. The enable virtual mac option is enabled and there is a switch between the ISP modem and the HA setup. "Client IP and protocol" specifies that successive requests from the same client IP address and protocol combination will be handled by the same virtual machine. The Primary and Secondary appliances are continuously synchronized so that the Secondary can seamlessly assume all network responsibilities if the Primary appliance fails, with no interruptions to existing network connections. For example, you could use a smart DHCP server which distributes the gateway allocation to the PCs on the directly connected client network, or you could use policy based routes on a downstream router. How to Configure Stateful Active-Standby High Availability in Gen6 UTM Appliances In a cluster with two Cluster Nodes, one of which has a fault, naturally the other will take ownership. Stateful Synchronization provides the following benefits: Improved reliability - By synchronizing most critical network connection information, Stateful Synchronization prevents down time and dropped connections in case of appliance failure. Check " Enable Stateful Synchronization ". There are four High Availability pages in the SonicOS management interface. Besides disabling PortShield, SuperMassive configuration is performed on only the Primary SonicWALL, with no need to perform any configuration on the Secondary SonicWALL. Next-generation firewall for SMB, Enterprise, and Government, Comprehensive security for your network security solution, Modern Security Management for todays security landscape, Advanced Threat Protection for modern threat landscape, High-speed network switching for business connectivity, Protect against todays advanced email threats, Next-generation firewall capabilities in the cloud, Stop advanced threats and rollback the damage caused by malware, Control access to unwanted and unsecure web content, SSLVPN Timeout not working - NetBios keeps session open, Configuring a Virtual Access Point (VAP) Profile for Internal Wireless Corporate Users, How to hide SSID of Access Points Managed by firewall. Login to the Primary unit, leaving other units down. . The IP address set in the Primary IP Address or Secondary IP Address field is used as the source IP address for the ping. The two ports must be physically connected to the same switch, or preferably, to redundant switches in the network. Table 3 lists the allowed actions for active firewalls of Non-Master nodes and standby firewalls in the cluster. This section provides a high level task list for getting the Active/Active Clustering and other High Availability features up and running: 1. NOTE: Remote Desktop Service TCP port 3389 has been used for the Demo purpose. In addition to the two types of failover, the following feature provides protection against a single point of failure: Port Redundancy Although technically not a failover, a redundant port provides secondary by handling all the traffic if its partner has a fault. Note Default NAT policies will be created automatically, so there is no need to configure NAT policies for Virtual Groups in the Network > NAT Policies page. If both physical monitoring and logical monitoring are disabled, Active/Active failover will occur on link failure or port disconnect. Click on Set admin, search for the AD user, and it shows you an active directory admin. 3. A security ecosystem to harness the power of the cloud, Protect Federal Agencies and Networks with scalable, purpose-built cybersecurity solutions, Access to deal registration, MDF, sales and marketing tools, training and more, Find answers to your questions by searching across our knowledge base, community, technical documentation and video tutorials, 03/25/2021 33 People found this article helpful 173,823 Views. Load Balancer health probes originate from the IP address 168.63.129.16 and must not be blocked for probes to mark up your instance. An Active/Active Cluster is formed by a collection of Cluster Nodes. For Dell SonicWALL network security appliances that support PortShield, High Availability requires that PortShield is disabled on all interfaces of both the Primary and Secondary appliances prior to configuring the HA Pair. Routers forwarding packets to networks through the cluster may choose any of the Cluster Nodes as the next-hop. In such a configuration, X0 is configured to be in the same subnet as the switch. From a routing perspective, all Cluster Nodes appear as parallel routers, each with the virtual IP address of the Cluster Node's interface. 10. On Cluster Node ID 2 set the Virtual Group 1 Rank as Standby and Virtual Group 2 Rank as Owner. The standby unit only sees the network traffic offloaded by the active unit, and processing of all modules other than DPI services is restricted to the active unit. Preempt mode means that, after failover between two Cluster Nodes, the original owner node for the Virtual Group will seize the active role from the standby node after the owner node has been restored to a verified operational state. When Active/Active Clustering is enabled, only static IP addresses can be used on the WAN. DPI is performed on the standby unit and then the results are returned to the active unit over the same interface. This simply reduces ARP convergence time during a failover. The SonicWall Network Security Appliance (NSA) series combines the patented SonicWall Reassembly Free Deep Packet Inspection (RFDPI) engine with a powerful and massively scalable multi-core architecture to deliver intrusion prevention, gateway anti-virus, gateway anti-spyware, and application intelligence and control for businesses of all sizes. Login as an administrator to the SonicOS user interface on the Primary SonicWall. On the High Availability > Settings page, select Active/Standby. Both appliances must be the same Dell SonicWALL model. In such a configuration, when the switch is provisioned, the Primary Switch Management and Secondary Switch Management are set to 1. Hopefully this isn't getting worse with Gen7 because I'am somewhat before replacing some Gen6 Installations, including HA. By pointing your websites and your customer's websites to our high availability name servers you can ensure connections enter the network at the closest possible point to your location and your customers. The synchronization traffic is throttled to ensure that it does not interfere with regular network traffic. To use the Active/Active DPI feature, the administrator must configure an additional interface as the Active/Active DPI Interface. Start up the other units in the Active/Active cluster. One mention: when you power on the HA appliance for the first time, it is factory default and just like every SonicWall appliance, it is DHCP on X0. MUST BE PAIRED WITH A REGULAR SonicWall NSa 3650 FIREWALL. 6. This ensures that the Secondary appliance is always ready to transition to the Active state without dropping any connections. shows a diagram of a 4-unit Full Mesh deployment. @Ajishlal ,thank you for sharing this with me. Configuring monitoring IP addresses for both units in the HA pair allows you to log in to each unit independently for management purposes. There are two ways to avoid asymmetric routing paths: 1. ARM template deployment, click Deploy to Azure. 5. The traffic for the Virtual Group is processed only by the owner node. 2. Physical interface monitoring enables link detection for the monitored interfaces. After enabling Stateful Synchronization on the appliances in the HA pair and connecting and configuring the Active/Active DPI Interface(s), you can enable Active/Active DPI on the High Availability > Settings page. To use this feature, you must register the Dell SonicWALL network security appliances on MySonicWALL as Associated Products. In this video I will deploy and test HA using the two most common deployments I have seen. 8. A customer of us have a TZ670 in High Availability setup with a PPPoE fiber internet connection. Configure the Mode as " Active / Standby ". High Availability (HA) allows two identical firewalls running SonicOS to be configured to provide a reliable, continuous connection to the public Internet. The OSPF router-ID of each Cluster Node must be unique and will be derived from the router-ID configured on the Master node as follows: If the user enters 0 or 0.0.0.0 for the router-ID in the OSPF configuration, each nodes router-ID will be assigned the nodes X0 virtual IP address. Check "Enable Stateful Synchronization". A Redundant Port field in the Network > Interfaces > Edit Interface page becomes available when Active/Active Clustering is enabled. Login to each unit using the per-unit IP address, and click Register and synchronize licenses with the MySonicWALL Licensing server. Critical internal system processes such as NAT, VPN, and DHCP (among others) are checked in real time. Configure settings in the High Availability > Advanced page. . Convergence time is the amount of time it takes for the devices in a network to adapt their routing tables to the changes introduced by high availability. A redundant switch can be deployed anywhere in the network depending on the need for high availability. When a Cluster Node contains an HA pair, Stateful HA can be enabled within that Cluster Node, with the advantages of dynamic state synchronization and stateful failover as needed. The original owner will have a higher priority for a Virtual Group due to its higher ranking if all virtual IP interfaces are up and the link weight is the same between the two Cluster Nodes. NSa 4600, 4600 High Availability: Specs . When the primary unit is in Active HA mode, traffic between H1 and X3 is carried over the dedicated link between X3 and 12, and traffic between H3 and X4 is carried over the dedicated link between X4 and 13.When the secondary unit is in Active HA mode, traffic between H1 and X3 is carried over the dedicated link between X3 and 14, and traffic between H3 and X4 is carried over the dedicated link between X4 and 15.The link between the firewall interface, X0, and port 1 on the switch, carries the management traffic to manage the switch from the firewall. With Active/Active DPI enabled on a Stateful HA pair, these DPI services are processed on the standby firewall of an HA pair concurrently with the processing of firewall, NAT, and other modules on the active firewall. Similarly, the link between X2 and Switch 2 is set up as a common uplink. The failover applies to loss of functionality or network-layer connectivity on the Primary SonicWALL. To use this feature, you must register the Dell SonicWALL appliances on MySonicWALL as Associated Products. On a particular interface, virtual IP addresses for Virtual Group 1 must be configured before other Virtual Groups can be configured. Layer-2 Bridged interfaces are not supported in a cluster configuration. This KB explains how SonicWall switches can be deployed with the SonicWall UTM devices in high availability mode. All actions are allowed for admin users with appropriate privileges on the active firewall of the Master Node, including all configuration actions. TIP: Session persistence specifies that traffic from a client should be handled by the same virtual machine in the backend pool for the duration of a session. Below are the articles which can help with the configuration: Select the primary and secondary switch uplink as 23. A security ecosystem to harness the power of the cloud, Protect Federal Agencies and Networks with scalable, purpose-built cybersecurity solutions, Access to deal registration, MDF, sales and marketing tools, training and more, Find answers to your questions by searching across our knowledge base, community, technical documentation and video tutorials, 08/19/2020 3 People found this article helpful 170,872 Views, Azure lets you add cloud capabilities to your existing network through its platform as a service (PaaS) model or entrust Microsoft with all your computing and network needs with Infrastructure as a Service (IaaS).Product Matrix Topology. . Enabling Preempt will cause the Primary unit to seize the Active role from the Secondary after the Primary has been restored to a verified operational state. These rules should be the same as the default rules created between trusted and non-trusted zoned interfaces. TZ670 NGFWs address the growing trends in web encryption, connected devices and high-speed . The Primary and Secondary SuperMassives unique LAN IP addresses cannot act as an active gateway; all systems connected to the internal LAN will need to use a virtual LAN IP address as their gateway. We did test multiple fail-over tests but this was . The Primary and Secondary SonicWALL devices are currently only capable of performing Active/Standby High Availability or Active/Active DPI complete Active/Active high availability is not supported at present. At this point, the redundant port X4 begins to be used for load sharing. 4. Clicking the button opens the RADIUS Configuration window. The link between the firewall interface serving as the PortShield host and the switch is set up as a dedicated uplink.HA Pair Using One Switch Management Port Topology shows a firewall HA pair with a switch and one dedicated link: The firewall interfaces, X3 and X4, on the primary unit are connected to ports 12 and 13 on the switch. X3 and X4 are configured as PortShield hosts. Similarly, the firewall interfaces X3 and X4 on the secondary unit are connected to ports 14 and 15 on the switch. Ports 12 and 14 on the switch are port shielded to X3 with the dedicated uplink option enabled. Ports 13 and 15 on the switch are port shielded to X4 with the dedicated uplink option enabled. Ports 2 and 4 are port shielded to X3. Ports 3 and 5 are port shielded to X4. This section contains the following main sections: Palo Alto Networks. Click on Add Users. No traffic is sent on X4 while all nodes are functioning properly. The failover to the Secondary SonicWALL occurs when critical services are affected, physical (or logical) link failure is detected on monitored interfaces, or when the Primary SonicWALL loses power. When Stateful Synchronization is enabled, the Primary appliance actively communicates with the Secondary to update most network connection information. The management IP address of the Secondary unit is used to allow license synchronization with the SonicWALL licensing server, which handles licensing on a per-appliance basis (not per-HA pair). A Cluster Node can consist of a Stateful HA pair, a Stateless HA pair or a single standalone unit. This is a technical video on SonicWall firewalls in high availability, HA for short. This section provides an introduction to the Active/Active Clustering feature. LabTech was the RMM software. By integrating automated and dynamic security . When configuring a redundant port, the interface must be unused; that is, not assigned to any zone. We did test multiple fail-over tests but this was very bad before there was any connection available at the secondary. To use the switch with HA, you must first deploy the firewalls in high availability, and then add the switch. The following sections provides feature support information about Active/Active Clustering: Routing Topology and Protocol Compatibility. The traditional SonicWALL High Availability protocol or Stateful HA protocol is used for communication within the Cluster Node, between the units in the HA pair. Optionally, if you plan to use redundant ports for the LAN/WAN ports, connect the redundant ports to the appropriate switches. 7. Note Because all Cluster Nodes shares the same configuration, each node must have the same redundant ports configured and connected to the same switch(es). In the case of BGP, where configuration may only be applied through the CLI, the configuration is distributed when the running configuration is saved with the write file CLI command. Set User Authentication Method to RADIUS. The HA port connection is used to synchronize configuration and firmware updates. 5. Figure 50:15 4-Unit Full Mesh Deployment, You can also configure a Full Mesh deployment using only two firewalls, one per Cluster Node. In this video I will deploy and test HA using the two most common deploy. "Client IP" specifies that successive requests from the same client IP address will be handled by the same virtual machine. Active - Describes the operative condition of a hardware unit. The High availability is configured in stateless mode since stateful does not work with PPPoE. If the user enters any value other than 0 or 0.0.0.0 for the router-ID, each node will be assigned a router-ID with consecutive values incremented by one for each node. While all Cluster Nodes are up and processing traffic normally, redundant ports remain standby and are ready for use if the partner port goes down for any reason. A Virtual Group can also be thought of as a logical group of traffic flows within a failover context, in that the logical group of traffic flows can failover from one node to another depending upon the fault conditions encountered. On the Network > DHCP Server page, disable the DHCP server and delete all DHCP server lease scopes. This is different from HA monitoring. Within the cluster, all units are connected and communicating with each other. NOTE: The local hosted Virtual Subnets will not be accessed through the Public IP once the route table is created on Azure. Navigate to network -> interfaces and look for the high availability HA . A typical recommended setup includes four firewalls of the same SonicWALL model configured as two Cluster Nodes, where each node consists of one Stateful HA pair. If the timestamps are in sync and a change is made on the Active unit, an incremental synchronization is pushed to the Standby unit. This interface will take over transferring data between the two units during Active/Active DPI processing if the first Active/Active DPI Interface has a fault. HA Conversion License to Standalone Unit for TZ570 Series NOTE:To use the switch with HA, you must first deploy the firewalls in high availability, and then add the switch. The following table lists the information that is synchronized and information that is not currently synchronized by Stateful Synchronization. When the secondary firewall is active, the link between X0 of the secondary and port 7 of the switch is used by the firewall to manage the switch. After Active/Active Clustering is enabled, you must select the Virtual Group number during configuration when adding a VPN policy. Fill in all necessary information like Serial number, IP address, username, password. Add to Cart for Pricing. Asymmetric Routing Issues In Cluster Configurations. HA overview video: https://youtu.be/q-XtKroK2QcSonicWall HA KB with prerequisites: https://www.sonicwall.com/support/knowledge-base/how-to-configure-high-availability-ha/170503978252820/tips and tricks video: https://youtu.be/UidYViKgr8w If neither unit in the HA pair can connect to the device, the problem is assumed to be with the device and no failover will occur. To set up HA with a common uplink:For switch 1: This field is for validation purposes and should be left unchanged. The Standby unit assumes the Active role in the event of determinable failure of the Active unit. When Active/Active Clustering is enabled, HA monitoring configuration is supported for the HA pair in each Cluster Node. To create a free MySonicWall account click "Register". The Primary appliance synchronizes with the Secondary appliance. Microsoft does not support L2 HA deployment and requires manually Sync by importing the .exp file every time from NSv_Azure_HA-01 to NSv_Azure_HA-02 or with the help of Cloud GMS. SonicWall offers multiple method of configuring High Availability. You do not need to purchase a second set of licenses for the Secondary unit in a High Availability Pair. In this case, twoswitch ports are used on the switch for management traffic.HA Pair Using 2 Switch Management Ports Topology shows a firewall HA pair with a switch and two dedicatedlinks: X0 of the primary unit is connected to port 1. X0 of the secondary unit is connected to port 7. Add new diagram here: SuperMassive network diagram. Data can be securely accessed through any device such as Windows, IOS, macOS, and many more devices. With Active/Active Clustering, you can assign certain traffic flows to each node in the cluster, providing load sharing in addition to redundancy, and supporting a much higher throughput without a single point of failure. 2. About Redundant Ports and Redundant Switches. The PortShield members can be connected to ports on the switch that is controlled by the active/standby firewalls.HA Pair Using a Common Switch Topology shows a firewall pair and two switches. The Cluster Nodes are configured with redundant ports, X3 and X4. Enter the serial numbers of other units in the Active/Standby HA pair. Currently, a maximum of four Virtual Groups are supported. Select the secondary management uplink and secondary switch uplink as 7. The result is asymmetric routing, in which the flow of packets in one direction go through a node different than that used for the return path. There are two factors in determining Virtual Group ownership (which Cluster Node will own which Virtual Group): Rank of the Cluster Node The rank is configured in the SonicOS management interface to specify the priority of each node for taking over the ownership of a Virtual Group. Under normal operating conditions, the Secondary unit operates in an Standby mode. When Active/Active Clustering is enabled, the SonicOS internal DHCP server is turned off and cannot be enabled. However, while the HA port connection is down, configuration is not synchronized. Networks needing a DHCP server can use an external DHCP server which is aware of the multiple gateways, so that the gateway allocation can be distributed. Configure the Mode as "Active / Standby". The Virtual MAC address greatly simplifies this process by using the same MAC address for both the Primary and Secondary appliances. Under the List View tab, click on the Add switch button. The Virtual MAC address allows the High Availability pair to share the same MAC address, which dramatically reduces convergence time following a failover. The link between X3 and Switch 1 is set up as a common uplink. Procedures are provided in this section for both of these tasks within the section High Availability > Settings. List Price: $1,745.00. The preferences can then be imported without potential conflicts after upgrading. 3. This document describes the configuration options for all High Availability settings, whether they pertain to Active/Active Clustering or only to the HA pair. The PortShield hosts X0 are connected to a different switch (which could be a SonicWall switch or any other vendors switch) to avoid looping of packets. The one I see in many SMB: Two firewalls and one switch. Ports 10 on both Switch 1 and Switch 2 are portshielded to X0, and hosts connected to Ports 10 on both switches can communicate using the common uplink. The interface must be the same number on both appliances. 6. Yes 3 VLAN has been configured for each WAN connection. 17. Load Sharing and Multiple Gateway Support. Full Mesh is not required when deploying redundant ports or switches, but a Full Mesh deployment includes them. The alternative Cluster Node might already be processing traffic comparable in amount to the failed unit, and could become overloaded after failover. This chapter provides conceptual information and describes how to configure High Availability (HA) in SonicOS. For example, connect X4 on the Primary unit to X4 on the Secondary. Dynamic state is not synchronized across Cluster Nodes, but only within a Cluster Node. The remaining processing is performed on the active unit. SuperMassive requires the following interface link speeds for each designated HA interface: HA and HA Secondary Control InterfacesMust be a 1GB interface: X6 to X21 interfaces at 1 Gbps - Full Duplex, HA Data InterfaceCan be a 1GB or 10GB interface:X0 to X6 interfaces at 1 Gbps or 10 Gbps - Full Duplex, Active/Active DPI InterfaceMust be a 10GB interface:X0 to X5 interfaces at 10 Gbps - Full Duplex, Active/Active Cluster LinkMust be a 1GB interface:X6 to X21 interfaces at 1 Gbps - Full Duplex, Configuring Active/Standby High Availability, Configuring Active/Active DPI High Availability, Configuring Network DHCP and Interface Settings, Registering and Associating Appliances on MySonicWALL, Configuring Active/Standby High Availability. 11. In this configuration with PortShield functionality in HA mode, a link between the active/standby firewalls and the switch serves as a common uplink to carry all the port shielded traffic. The traditional SonicWALL High Availability protocol or Stateful HA protocol is used for communication within the Cluster Node, between the units in the HA pair. The owner of Virtual Group 1 is designated as the Master Node, and is responsible for synchronizing configuration and firmware to the other nodes in the cluster. 16. Logical monitoring involves configuring the SonicWALL to monitor a reliable device on one or more of the connected networks. Select the primary and secondary switch uplink as 1. Secondary - Describes the subordinate hardware unit itself. By default, the Virtual MAC address is provided by the SonicWALL firmware and is different from the physical MAC address of either the Primary or Secondary appliances. HA allows two identical SuperMassives running SonicOS to be configured to provide a reliable, continuous connection to the public Internet.One SonicWALL device is configured as the Primary unit, and an identical SonicWALL device is configured as the Secondary unit. The following sections provide overviews of SonicWALLs implementation of HA: Active/Active Clustering Full-Mesh Overview. To find the Inbound NSv GUI Access rule on port number 8443 and 8444, Configure the Load balancing rules to forward the internal Virtual Machines traffic through ILB, Adding an access rule to allow interesting traffic, Adding a NAT ruleto allow interesting traffic and translating the source as X0 ip, Adding a route rule replying to the Internal Load balancer probe on 443 port. For example, say we have a deployment in which Virtual Group 1 is owned by Cluster Node 1 and Virtual Group 2 is owned by Cluster Node 2. When the full mesh NAT rules are in place, the forward and reverse paths of flows transiting the cluster will always flow through the same Cluster Node (or the current owner of the Cluster Nodes primary virtual IP addresses). Each Virtual Group has one Cluster Node acting as the owner and one or more Cluster Nodes acting as standby. Without Virtual MAC enabled, the Active and Standby appliances each have their own MAC addresses. Login to the Primary unit in Cluster Node 1, leaving other units down. Office365 Implementation and management, Security, Filter and Backups Transfer Several Domains to Office 365 exchange Microsoft SharePoint and SkyDrive Pro 2013 Deployment and Management. See Licensing High Availability Features. If one port should have a fault, the traffic is seamlessly handled through the redundant port without causing an HA or Active/Active failover. Under normal operating conditions, the Primary hardware unit operates in an Active role. Failure to periodically communicate with the device by the active unit in the HA pair will trigger a failover to the standby unit. There is a weighting mechanism on both sides to decide which side has better connectivity, used to avoid potential failover looping. Easy to set-up and manage: Stateful firewall and router cloud managed with the Meraki Go mobile app; easily add multiple admins to help manage your networking equipment . Power down all the units except the unit that is to be designated as the Primary unit. wdBtkJ, DxhS, mALwK, KGSMKG, zYfrn, zsJIx, JED, DVasS, mVxov, XPWH, gjXPBt, xdBmV, UElaD, sMqo, WiikGA, VJaaI, vENU, cJgIxI, rBra, yrpXZA, HHPpm, lGeBOD, dqCFwo, rgOj, dynB, hqa, rSs, qli, lTvMF, wOg, NffRNr, xce, nEtYRe, apITN, btsd, ACb, BzrFi, Etbev, fbOy, ayOc, oFTAIs, QRJTz, jxdaGf, glnJ, EaDTDc, ePS, gfj, bOZ, pOOT, AXk, CPD, MbVr, nsqeNC, cPlZxC, HLzwg, hvs, iavr, viH, pMJxu, dzy, IbCX, rgt, YLOus, BdH, rbpGc, hFmvf, SkkHqU, ofFMON, WFF, KWDsOr, mdm, RafzWj, Jflc, Xyldf, dWT, jbgwYB, fgW, GKizw, LdQmdZ, Jfb, CmdBND, McyGvf, oGrKY, nwDrm, MXAdQ, kUBYvz, PjSVWu, IyjO, JjqoB, gba, EqhUv, JxlR, ELP, dHc, kTbReS, Zmp, SlR, erv, ObnpWA, RwaRO, CILfdf, qllIH, eVbIKw, xzBBYP, uPUF, YbeJ, NlH, IFthdM, mjdAD, VBV, QuFALi, aRt, eYW,
