The configuration tasks on the High Availability > Monitoring page are performed on the Primary This section describes the physical connections needed for Active/Active Clustering and Active/Active DPI. Security & VPN: PIX 500 Firewall, ASA 5505 Firewall, AIP SSM, CSC SSM, FWSM, Fort Confidential, CISCO CSM, ACL- Access Control List, IPS/IDS, NAT, PAT, CISCO ACS, Check point, sonicwall, RSA Secure ID, SRX,SSG series firewalls. Each additional virtual IP address is associated with one of the other Virtual Groups in the cluster. Failure to periodically communicate with the device by the Active unit in the HA Pair will trigger a failover to the Idle unit. To verify that Primary and Backup SonicWALL security appliances are functioning correctly, In the Primary IPv4 Address field, enter the unique LAN management IP address of the Primary unit. pfSense and SonicWall VPN problem with multiple subnets Security I was setting up some VPN's the other day, and I came across a . Enter the rank that Cluster Node 1 holds for each Virtual Group in the Virtual Group X Rank fields to the right of the serial numbers. These rules should be the same as the default rules created between trusted and non-trusted zoned interfaces. ::). Another method is by using policy based routes on a downstream router. VLAN interfaces can also have up to four virtual IP addresses. Once you finish configuring the High Availability settings on the Primary SonicWALL security On the Advanced tab, you can select the Virtual Group number for the VPN Policy Group setting. 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. 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. Figure 50:21 Log > View Page Showing High Availability Events, Configuring VPN and NAT with Active/Active Clustering. and Secondary IP Address High Availability > Monitoring Add the Virtual Group (VG) IP addresses for both the X0 and X1 interfaces. set vpn l2tp authentication set vpn l2tp authentication. Active/Active DPI can be enabled, providing increased throughput within each Cluster Node. For example, every SonicWALL firewall uses redundant ports to connect twice to each networking device. (If probing is desired on the WAN side, an upstream device should be used.) With port redundancy, a backup link will take over in a transparent manner if the primary port fails. 8. On the High Availability > Monitoring page, add the monitoring/management IP addresses either on X0 or X1 for each unit in the cluster. Link Failures: Traffic should continue to flow in each of the following link failures: a. The following sections describe High Availability monitoring: On the b. Because the connection between the Primary and Backup units is typically protected, this is generally not a security concern. The management IP address of the Secondary/Standby unit is used to allow license synchronization with the SonicWALL licensing server, which handles licensing on a per-appliance basis (not per-HA Pair). 4. Failure to periodically communicate with the device by the Active unit in the HA Pair will trigger a failover to the Idle unit. If both can successfully ping the target, no failover occurs. This section describes the procedure for setting up an Active/Active Cluster Full-Mesh deployment. 4. You can assign an unused physical interface as a redundant port to a configured physical interface called the primary interface. (If probing is desired on the WAN side, an upstream device should be used.) In the setup described above, X2 is the redundant port of X0. Note that the Secondary appliance of the HA pair is referred to as the HA Secondary unit on MySonicWALL. Unless live communication with SonicWALL's licensing server is not permitted due to network policy, the WAN (X1) interface should be connected before registration and licensing are performed. You can assign multiple virtual IP addresses to each interface, one per Virtual Group. The management IP address of the Secondary/Standby unit is used to allow license synchronization with the SonicWall licensing server, which handles licensing on a per-Security Appliance basis (not per-HA Pair). All firewall and other network devices are partnered for complete redundancy. Audio/Video Cables; Ethernet Cables; Network Cables 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). Typically, this should be a downstream router or server. Cable Switch A and Switch B together. CPU activity goes down on the active unit, and goes up on the standby unit. To configure a redundant port for an interface: 2. Enter the rank that Cluster Node 1 holds for each Virtual Group in the Virtual Group X Rank fields to the right of the serial numbers. shows a diagram of a four-unit cluster. in the upper right corner. You can also use URL filtering to enforce safe search settings for your users, and to prevent credential phishing based on URL category. High Availability related log events can be viewed in the Log > View page. In the Logical Probe IP Address field, enter the IP address of a downstream device on the LAN network that should be monitored for connectivity. For best practice, use the same set of interfaces on each unit in each node. Each Virtual Group has one Cluster Node acting as the owner and one or more Cluster Nodes acting as standby. page to connect to the SonicWALL server while accessing the Backup appliance through its management IP address. Login to your MySonicWALL account at <. fields must be configured with independent IP addresses on a LAN interface, such as X0, (or a WAN interface, such as X1, for probing on the WAN) to allow logical probing to function correctly. The Primary and Backup IP addresses configured on this page are used for multiple purposes: Configuring unique management IP addresses for both units in the HA Pair allows you to log in In each Cluster Node, only the active unit processes the SVRRP messages. 3. Physical monitoring cannot be disabled for these interfaces. 4. 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. Link Failures: Traffic should continue to flow in each of the following link failures: a. All Cluster Nodes share the same configuration as the Master node. b. A note indicates that it is a redundant Port and lists the primary interface. 8. The Active/Active Clustering Node Status table is shown below. To copy the license keyset to the clipboard, press Ctrl+C. Configuring Active/Active Cluster Firewalls. Full Mesh deployments provide a very high level of availability for the network, because all devices have one or more redundant partners, including routers, switches, and security appliances. The selected interface will be greyed-out in the Interface Settings table. target from the Primary as well as from the Backup SonicWALL. Note In addition to the requirements described in this section, ensure that you have completed the prerequisites described in Active/Standby and Active/Active DPI Prerequisites. For example, when the Backup SonicWALL takes over for the Primary after a failure, an email alert is sent indicating that the Backup has transitioned from Idle to Active. SonicWALL recommends disabling preempt mode when using Stateful High Availability. 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. Dynamic state synchronization is only available in a Cluster Node if it is a Stateful HA pair. Load Sharing and Multiple Gateway Support. To physically connect your network devices for a full-mesh deployment, perform the following steps: 1. Go to the Network > Interfaces page to verify that you have successfully configured the Active/Active interfaces that you want. Login to the Primary unit of the Cluster Node and navigate to the Network > Interfaces page. When Interface Monitoring is enabled and configured, if any of the monitored interfaces loses connectivity on the active unit and is still reachable on the idle unit, failover occurs. 4. If both units can successfully ping the target, no failover occurs. In the setup described above, we also use Active/Active DPI along with Active/Active Clustering. For example, when an SMTP session carries a virus attachment, SonicOS sends the SMTP client a 552 error response code, with a message saying the email attachment contains a virus. A TCP reset follows the error response code and the connection is terminated. There are several important concepts that are introduced for Active/Active Clustering. (If probing is desired on the WAN side, an upstream device should be used.) SVRRP management messages are initiated on the Master Node, and monitoring information is communicated from every appliance in the cluster. Routers forwarding packets to networks through the cluster may choose any of the Cluster Nodes as the next-hop. These NAT policies extend existing NAT policies for particular interfaces to the corresponding virtual interfaces. 6. For example, select X4 for the redundant port. I am getting: Received notify. When running in Active/Active Clustering mode, NAT policy configuration includes Virtual Group settings. High Availability related log events can be viewed in the Log > View page. For Active/Active Clustering, additional physical connections are required: Active/Active Cluster LinkEach Active/Active cluster link must be a 1GB interface. 14. The two appliances in each HA pair must also be associated as HA Primary and HA Secondary on MySonicWALL. Troubleshoot an OTP Deployment. After Active/Active Clustering is enabled, you must select the Virtual Group number during configuration when adding a VPN policy. 1. 3. Figure64:24 Responses, or actions, are always sent out from the active unit of the Stateful HA pair running Active/Active DPI when DPI matches are found in network traffic. Default NAT policies are created by SonicOS when virtual IP addresses are added, and are deleted when the virtual IP is deleted. In any High Availability deployment, you must physically connect the LAN and WAN ports of all units to the appropriate switches. generating a Tech Support Report on the System > Diagnostics page. 12. Although the Palo Alto Networks URL filtering solution supports both BrightCloud and PAN-DB, only the PAN-DB URL filtering solution allows you to choose between the PAN-DB Public Cloud and the PAN-DB Private . Full-Mesh ensures that there is no single point of failure in your deployment, whether it is a device (firewall/switch/router) or a link. SVRRP management messages are initiated on the Master Node, and monitoring information is communicated from every appliance in the cluster. Add the redundant port configuration (X2 as redundant port of X0, X3 as redundant port of X1). Within each Cluster Node, Stateful HA keeps the dynamic state synchronized for seamless failover with zero loss of data on a single point of failure. See High Availability > Monitoring for information about configuring the individual IP addresses. 6. In the Primary IP Address field, enter the unique LAN management IP address of the Primary unit. When this option is enabled for an interface, a green icon appears in the interfaces Management column in the Monitoring Settings table on the High Availability > Monitoring page. Call 317-225-4117 to check product availability. There is also a way to synchronize licenses for an HA pair whose appliances do not have Internet access. 4. Care must be taken when choosing the Virtual MAC address to prevent configuration errors. Involved in the Team of Data Centre Operations to perform duties like administration and monitoring of Cisco Routers and Switches according to the organization requirements. For example, This section describes several methods of verifying the correct configuration of Active/Active Clustering and Active/Active DPI. Logical monitoring involves configuring the SonicWALL to monitor a reliable device on one or more of the connected networks. On each of the Active firewalls in the Cluster Node, disconnect the X1 cable while X3 is connected. The Primary and Secondary appliances will regularly ping this probe IP address. One advantage of this feature is that in case of a physical link failure, there is no need to do a device failover. 3. 5. 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. Active/Active Clustering requires additional configuration of virtual IP addresses for additional Virtual Groups. In the Mode pull-down menu, select Active/Active DPI Clustering. The HA port connection is also used to synchronize configuration from the Master Node to the other Cluster Nodes in the deployment. Active/Standby High Availability Monitoring, Configuring Active/Standby High Availability Monitoring. This ensures seamless operation and it appears as if the DPI processing was done on the active firewall. Benefits of Active/Active Clustering Full Mesh. on the left side of the browser window and then click Restart In Policy Type: Choose Site to Site. Allowing the SonicOS firmware to generate the Virtual MAC address eliminates the possibility of configuration errors and ensures the uniqueness of the Virtual MAC address, which prevents possible conflicts. Click Advanced Settings on the left. Primary IP Address High Availability SecureFirst Partners should login via the designated box below to access a broader variety of courses, curricula and partnering materials. From a routing perspective, all Cluster Nodes will appear as parallel routers with the virtual IP address of the Cluster Nodes interface. If neither unit in the HA Pair can connect to the device, no action will be taken.

Active/Active Clustering Full-Mesh Overview. Enable Spanning Tree, but also enable Port Fast (or equivalent command) on the ports connected to the firewalls. 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. For more information about the HA Monitoring settings, see About HA Monitoring. 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. 2. When viewing the Multi-Core Monitor on an active unit in the cluster, all firewalls in the cluster are displayed. In the event of a failure in the Primary SonicWALL, you can access the management interface The General tab is displayed. If the owner node for a Virtual Group encounters a fault condition, one of the standby nodes will become the owner. shows the NAT policy automatically created for Virtual Group 2 on interface X1. This will cause traffic to be dropped by one or both Cluster Nodes since neither is seeing all of the traffic from the flow. Click on Add Users. 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. The management interface should Now we can test for no single point of failure on all devices and links with the following steps: 1. On the High Availability > Settings page: b. We are in need of connecting 1 office to another via VPN . In the table, enter the serial numbers of the appliances in each Cluster Node. The designated HA ports on the two appliances are connected directly to each other using a cross-over cable. Reason is that we have two public servers only accessible from one location where the Sonicwall is. While it is possible to connect a redundant switch without using a redundant port, this involves complex configuration using probes. These Virtual Group address objects are created by SonicOS when virtual IP addresses are added, and are deleted when the virtual IP is deleted. Price alert. These additional TCP packets are generated as a result of the DPI processing on the standby firewall. Verifying Settings in the High Availability > Status Page The High Availability > Status page provides status for the entire Active/Active cluster and for each Cluster Node in the deployment. 6. Ports X6 and X7 are the two HA data ports for redundancy and load-sharing of offloaded traffic from Active to Standby firewalls. To configure a virtual IP address on an interface: 1. By default, the 3. This allows the Secondary units to synchronize with the SonicWALL licensing server and share licenses with the associated Primary appliances in each HA pair. To configure monitoring on any of the other interfaces, repeat the above steps. Perform the following cabling (X6,X7 ports and cabling have not been shown in the above diagram for brevity): a.Connect X6 of CN1-Primary to X6 of CN1-Backup with a Cross-over cable. 10. This configuration utilizes all units in the cluster for the highest possible performance. If the Router A and Router B have redundant port support, then connect the Routers to Switches in the same way as we connected the Firewall ports to Switches. Example: Active/Active Clustering Two-Unit Deployment. On the High Availability > Monitoring page, you can configure independent management IP addresses for each unit in the HA Pair, using either LAN or WAN interfaces. Log into the Stateful HA pair using the shared IP address. f.: Shut down Router A while Router B is up and ready. 4. The link is sensed at the physical layer to determine link viability. 11. Login as an administrator to the SonicOS management interface on the Master Node. Dynamic state is not synchronized across Cluster Nodes, but only within a Cluster Node. 2. addition to other status messages and possible security threats. When finished with all High Availability monitoring configuration for the selected Cluster Node, click Apply. 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. In Authentication Method: Choose IKE Using . Login to the Primary unit of the Master Cluster Node and navigate to the High Availability > Settings page. Active/Active Clustering with Full-Mesh provides the highest level of availability possible with high performance. This prevents the need for device level failover. 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. Login as an administrator to the SonicOS user interface on the Primary SonicWALL. The generated packets are sent to the active firewall over the HA data interface, and are sent out from the active firewall as if the processing occurred on the active firewall. 3. However, if you log into the individual IP address of an standby unit in the cluster, the Multi-Core Monitor page only displays the core usage for the two firewalls in that particular HA pair. Even if the Secondary unit was already registered on MySonicWALL before creating the HA association, you must use the link on the System and Backup IP Address However, while the Active/Active Cluster links are down, configuration is not synchronized. Virtual Group 1 traffic is sent on X3, while Virtual Group 2 traffic is sent on X4. Cable Switch A and Switch B together. For information about physically connecting redundant ports and redundant switches, see the Active/Active Clustering Full Mesh Deployment Technote. Using a standard Ethernet cable, connect the two interfaces directly to each other. The two units in each HA pair are also connected to each other using another interface (shown as the Xn interface). 2. . 9. In the SonicOS management interface, navigate to the Network > Interfaces page and ensure that the Zone is Unassigned for the intended Active/Active DPI Interface. 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. This diagram shows a two-unit cluster. 1. b. Management is only allowed on an interface when this option is enabled. This is the Active/Active DPI Interface necessary for Active/Active DPI. on the left navigation pane of the management interface. In the Interface Settings table, click the configure icon for the interface you want to configure. Navigate to the System > Diagnostics page. Sonicwall TZ-500 - F/W Ver: 6.2 Thanks Shmid. For Active/Active Clustering, you must physically connect the designated HA ports of all units in the Active/Active cluster to the same Layer 2 network. A Full Mesh deployment uses redundant ports on each of the main traffic ports (LAN, WAN, etc. When configuring a redundant port, the interface must be unused; that is, not assigned to any zone. Configure DirectAccess with OTP Authentication. Certain packet flows on the active unit are selected and offloaded to the standby unit on the Active/Active DPI Interface. When the Enable Virtual MAC checkbox is selected on the High Availability> Advanced page, the SonicOS firmware automatically generates a Virtual MAC address for all interfaces. For example, you could connect X5 on the Primary unit to X5 on the Secondary if X5 is an unassigned interface. Repeat this procedure for the other appliance in the HA pair. This section describes the steps to configure the Active/Active Cluster firewalls. In the lower section of the page, shown in Active/Active Clustering configuration can include configuring Virtual Group IDs and redundant ports. If DPI UTM processing on the idle firewall results in a DPI match action as described above, The SonicWALL Virtual Router Redundancy Protocol (SVRRP) uses this HA port connection to send Cluster Node management and monitoring state messages. Configuring Active/Active Clustering High Availability Monitoring. This prevents the need for device level failover. 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. When a match is made, SonicOS performs an action such as dropping the packet or resetting the TCP connection. Note The primary and redundant ports must be physically connected to the same switch, or preferably, to redundant switches in the network. The Active/Active Clustering node status is displayed at the top of the page, and shows values for the following settings: Node Status Active or Standby for each node in the cluster, Primary A/A Licensed Yes or No for each node in the cluster, Secondary A/A Licensed Yes or No for each node in the cluster. 9. As independent management addresses for each unit (supported on all physical interfaces), To allow synchronization of licenses between the Idle unit and the SonicWALL licensing, As the source IP addresses for the probe pings sent out during logical monitoring, Configuring unique management IP addresses for both units in the HA Pair allows you to log in, The management IP address of the Backup/Idle unit is used to allow license synchronization, When using logical monitoring, the HA Pair will ping the specified Logical Probe IP address, To set the independent LAN management IP addresses and configure physical and/or logical. From your management workstation, test connectivity through the Backup SonicWALL by 2. 2. You can specify a Virtual Group or select Any when creating custom NAT policies. When physical interface monitoring is enabled, with or without logical monitoring enabled, HA failover takes precedence over Active/Active failover. Configuring unique management IP addresses for both units in the HA Pair allows you to log in to each unit independently for management purposes. Figure 62:11 Active/Active Two-Unit Cluster. To configure Active/Active DPI Clustering High Availability: If you have physically connected the Active/Active DPI Interface as described in Physically Connecting Your Appliances, you are ready to configure Active/Active DPI in the SonicOS management interface. 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. How Does Active/Active Clustering Work? of the Backup SonicWALL at the Primary SonicWALL virtual LAN IP address or at the Backup SonicWALL LAN IP address. 1. However, until you apply the licenses to the appliance, it cannot perform the licensed services. In a typical configuration, each Cluster Node owns a Virtual Group, and therefore processes traffic corresponding to one Virtual Group. To set the independent LAN management IP addresses and configure physical and/or logical interface monitoring, perform the following steps: 1. to configure the individual IP addresses. 15.9 How to see which IP addresses the Squid proxy is listening on. mason county press obituaries. Under DHCP Server Lease Scopes, select the checkbox at the top left corner of the table heading to select all lease scopes in the table. Asymmetric Routing Issues In Cluster Configurations. For more information about physically connecting redundant ports and redundant switches, see the Active/Active Clustering Full Mesh Deployment Technote. If both can successfully ping the target, no failover occurs. The Primary and Secondary IP addresses configured on this page are used for multiple Figure 50:19 Active/Active Clustering Node Status Table. This IP routing behavior presents problems for a firewall cluster because the set of Cluster Nodes all provide a path to the same networks. The interface also appears in the Redundant Port field in the Edit Interface window of the primary port. When finished with all High Availability monitoring configuration for the selected Cluster Node, For additional information on verifying the configuration, see, Verifying Active/Active Clustering Configuration, This section describes several methods of verifying the correct configuration of Active/Active, Comparing CPU Activity on Appliances in a Cluster, On the active firewall of the Master node, the System > Diagnostics page with Multi-Core, System > Diagnostics Page for Multi-Core Monitor, When Active/Active DPI is enabled on a Stateful HA pair, you can observe a change in CPU, When viewing the Multi-Core Monitor on an active unit in the cluster, all firewalls in the cluster, To see the core usage for all firewalls in the cluster, SonicWALL recommends viewing the, Verifying Settings in the High Availability > Status Page, The High Availability > Status page provides status for the entire Active/Active cluster and for, The Active/Active Clustering node status is displayed at the top of the page, and shows values, The Active/Active Clustering Node Status table is shown in, Active/Active Clustering Node Status Table, In the lower section of the page, shown in, You can tell that Active/Active DPI is correctly configured on your Stateful HA pair by generating. 5. Active/Active failover always operates in Active/Active preempt mode. 4. At the top right side of the page, select the. We will go over the following aspects of the deployment: Configuring the Active/Active Cluster Firewalls. As soon as Active/Active UTM is enabled on the Stateful HA pair, you can observe a change in firewall. On the High Availability > Monitoring page, you can configure independent management IP addresses for each unit in the HA Pair, using either LAN or WAN interfaces. OSPF is supported with Active/Active Clustering. For Remote Device Type, select FortiGate. Hardware Software Brands Solutions Explore SHI Tools 888-764-8888 Cables. If you add a new security service license, the keyset is updated. The Primary and Secondary IP addresses configured on DEVICE | High Availability > Monitoring can be configured on LAN or WAN interfaces, and are used for multiple purposes: Configuring unique management IP addresses for both units in the HA Pair allows you to log in to each unit independently for management purposes. Active/Active Clustering with Full-Mesh provides the highest level of availability possible with high performance. If there is a physical link failure on the primary interface, the redundant interface can continue processing traffic without any interruption. The SonicWALL Virtual Router Redundancy Protocol (SVRRP) uses this HA port connection to send Cluster Node management and monitoring state messages. Note To see the core usage for all firewalls in the cluster, SonicWALL recommends viewing the Multi-Core Monitor page on the active unit of the Master node. Repeat this procedure for the other appliance in the HA Pair. Note Because all Cluster Nodes share the same configuration, each node must have the same redundant ports configured and connected to the same switch(es). 4. 7. For detailed procedures describing the association process on MySonicWALL, see the High Availability chapter in the SonicOS Administrators Guide, available on:http://www.sonicwall.com/us/Support.html. Figure 62:10 Active/Active Four-Unit Cluster. The Backup SonicWALL security appliance should quickly take over. attachments, Application Firewall policies, and other malware.
