The following sections describe High Availability monitoring: On the 2. > Settings NO_PROPOSAL_CHOSEN. In the Primary IP Address field, enter the unique LAN management IP address of the Primary unit. 6. Layer-2 Bridged interfaces are not supported in a cluster configuration. Navigate to Groups Tab, under the Member Of, Add SONICWALL Administrator. You can use a dedicated switch or simply use some ports on an existing switch in your internal network. Figure 50:28 Active/Active Two-Unit Cluster, Configuring Network DHCP and Interface Settings. interface monitoring, perform the following steps: The When a match is made, SonicOS performs an action such as dropping the packet or resetting the TCP connection. The same interface must be selected on each appliance. By default, the But, if one appliance can ping the target and the other appliance cannot, failover will occur to the appliance that can ping the target. SVRRP is used to communicate Virtual Group link status and ownership status to all Cluster Nodes in the cluster. For information about physically connecting redundant ports and redundant switches, see the Active/Active Clustering Full Mesh Deployment Technote. Step 5 On the Systems > Licenses page under Manage Security Services Online , verify the services listed in the Security Services Summary table. When Local Certificates are copied to the Backup unit, the associated Private Keys are also copied. No switch is necessary in this case. Even if the Secondary unit was already registered on MySonicWALL before creating the HA association, you must use the link on the System 3. Perform the procedure for each of the appliances in a High Availability Pair while logged into its individual LAN management IP address. There is no Switch required for connecting the HA ports (since there are only two, they can be directly connected with a cross over cable). If there is a physical link failure on the primary interface, the redundant interface can continue processing traffic without any interruption. From a routing perspective, all Cluster Nodes will appear as parallel routers with the virtual IP address of the Cluster Nodes interface. After configuring HA Monitoring for IPv6, both the primary and backup appliances can be managed from the IPv6 monitoring address, and IPv6 Probing is capable of detecting the network status of HA pairs. To view the SonicWALL log, click Log 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. These NAT policies extend existing NAT policies for particular interfaces to the corresponding virtual interfaces. You can assign an unused physical interface as a redundant port to a configured physical interface called the primary interface. c.Connect X6 of CN2-Primary to X6 of CN2-Backup with a Cross-over cable. The HA port connection is also used for configuration synchronization between Cluster Nodes. A Cluster Node can consist of a Stateful HA pair, a Stateless HA pair or a single standalone unit. The HA port connection is also used for configuration synchronization between Cluster Nodes. 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. Click DOWNLOAD. Availability Pair must be individually registered from the SonicOS management interface while the administrator is logged into the individual management IP address of each appliance. Note Active/Active Clustering and Stateful High Availability licenses must be activated on each appliance, either by registering the unit on MySonicWALL from the SonicOS management interface, or by applying the license keyset to each unit if Internet access is not available. When the traffic setup is done, both Cluster Nodes will actively process network traffic. The Redundant Port field is only available when Active/Active Clustering is enabled. Compare. Note The routers in the firewalls upstream network should be pre-configured for Virtual Router Redundancy Protocol (VRRP). To exclude an appliance from a cluster, select None for the Virtual Group X Rank. 18. You can unsubscribe at any time from the Preference Center. On the Advanced tab, you can select the Virtual Group number for the VPN Policy Group setting. Go to the High Availability > Status page to verify your settings for Active/Active Clustering. Note The routers in the firewalls upstream network should be pre-configured for Virtual Router Redundancy Protocol (VRRP). VLAN interfaces can also have up to four virtual IP addresses. Try to configure the PRTG SNMP SONICWALL SYSTEM HEALTH SENSOR, It will give you the sonicwall health as same as below; Connection Cache Used CPU Usage Downtime Memory Usage MitatOnge Cybersecurity Overlord Hi Jason, you can find the high availability sensors in the "SONICWALL-FIREWALL-TRAP-MIB.MIB" file at Sonicwall download center. purposes: Configuring unique management IP addresses for both units in the HA Pair allows you to log in Additional NAT policies can be configured as needed and can be made specific to a Virtual Group if desired. At the top right side of the page, select the. When live communication with SonicWALL's licensing server is not permitted due to network policy, In a High Availability deployment without Internet connectivity, you must apply the license, Activating Licenses from the SonicOS User Interface. See High Availability > Monitoring for information about configuring the individual IP addresses. Power down Switch A while Switch B is up and ready. 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. In the Secondary IP Address field, enter the unique LAN management IP address of the Secondary unit. Failure to periodically communicate with the device by the Active unit in the HA Pair will trigger a failover to the Standby unit. On the Systems > Licenses page under Manual Upgrade, press Ctrl+V to paste the license keyset into the Or enter keyset text box. Even if the Backup unit was already registered on MySonicWALL before creating the HA association, you must use the link on the System MySonicWALL provides several methods of associating the two appliances. This section describes two methods of verifying the correct configuration of Active/Active UTM, Comparing CPU Activity on Both Appliances, As soon as Active/Active UTM is enabled on the Stateful HA pair, you can observe a change in, You can tell that Active/Active UTM is correctly configured on your Stateful HA pair by. In Authentication Method: Choose IKE Using . The table displays the following information: If you have configured the Primary SonicWALL to send email alerts, you receive alert emails If neither can successfully ping the target, no failover occurs, because it is assumed that the problem is with the target, and not the firewalls. 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). Restart SonicWALL Do this after you have linked them in MySonicWall. After the above deployment is connected and configured, CN1 will own Virtual Group1 (VG1), and CN2 will own Virtual Group 2 (VG2). As the Master Node synchronizes new firmware to other appliances in the cluster, secondary units are created on those appliances. This ensures seamless operation and it appears as if the DPI processing was done on the active firewall. When Internet access is restricted, you can manually apply the shared licenses to both appliances. Clear the Enable DHCP Server checkbox. 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). When live communication with SonicWALL's licensing server is not permitted due to network policy, you can use license keysets to manually apply security services licenses to your appliances. 4. 12. 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. For example, These additional TCP packets are generated as a result of the DPI UTM processing on the idle. Active/Active Clustering Full-Mesh Overview. Management is only allowed on an interface when this option is enabled. To force such a transition, it is necessary to interrupt the heartbeat from the currently Active for the following settings: The Active/Active Clustering Node Status table is shown in For additional information on verifying the configuration, see Verifying Active/Active Clustering Configuration. c.Select CN1 as Owner for Virtual Group 1 and Standby for Virtual Group 2. d.Select CN2 as Owner for Virtual Group 2 and Standby for Virtual Group 1. f.: Enable Active/Active DPI with X6 and X7 as the two HA data ports. Now we can test for no single point of failure on all devices and links with the following steps: 1. Example: Active/Active Clustering Four-Unit Deployment, Example: Active/Active Clustering Two-Unit Deployment. You need only purchase a single set of licenses for each HA Primary appliance. Active/Active Clustering with Full-Mesh provides the highest level of availability possible with high performance. See the following sections for descriptions of these new concepts and changes to existing functionality: About DPI with Active/Active Clustering, About High Availability Monitoring with Active/Clustering. 6. Installed high availability Big IP F5 LTM and GTM load balancers to provide uninterrupted . Set up HA as described in the HA topics. A complete synchronization of the configuration is made from the CN1-Primary to all other firewalls. The Primary IP Address and Secondary IP Address 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. That is, associate the two appliances in the HA pair for Cluster Node 1, then associate the appliances in the HA pair for Cluster Node 2, and so on for any other Cluster Nodes. I have created the VPN and both ends show green and are connected, so I believe that the security protocols match, however,. The link is sensed at the physical layer to determine link viability. To configure a virtual IP address on an interface: 1. Within the cluster, all units are connected and communicating with each other. Just select the IPv6 radio button and refer to High Availability Overview for configuration details. If the Primary SonicWALL subsequently resumes operation after that failure, and Preempt Mode has been enabled, the Primary SonicWALL takes over and another email alert is sent to the administrator indicating that the Primary has preempted the Backup. After the appliances are associated as an HA pair, they can share licenses. At this point, the redundant port X4 begins to be used for load sharing. Configuring Active/Active Clustering High Availability Monitoring, Configuring Active/Active Clustering High Availability. 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. About High Availability Monitoring with Active/Clustering. This specifies that Certificates, CRLs and associated settings (such as CRL auto-import URLs and OCSP settings) are synchronized between the Primary and Backup units. No switch is necessary in this case. Select External if the configured secondary appliance is part of a different cluster node. Login to your MySonicWALL account at . 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. The Master Node is also responsible for synchronizing firmware to the other nodes in the cluster. Cable Switch A and Switch B together. Then connect one port to Switch C and the other port to Switch D. Do a similar configuration for Router B. Ports X6 and X7 are the two HA data ports for redundancy and load-sharing of offloaded traffic from Active to Standby firewalls. Instead, each Cluster Node contains a single appliance. Configuring Active/Active Clustering Full Mesh. Redundant ports can be used along with Active/Active Clustering. 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. a. In the second row, enter the rank that Cluster Node 2 holds for each Virtual Group in the Virtual Group X Rank fields to the right of the serial numbers. When Active/Active DPI is enabled on a Stateful HA pair, you can observe a change in CPU utilization on appliances in the HA pair. 7. 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. In the Secondary IP Address field, enter the unique LAN management IP address of the Secondary unit. For more information about the HA Monitoring settings, see About HA Monitoring. DPI is performed on the standby unit and then the results are returned to the active unit over the same interface. b. unit and then are automatically synchronized to the Secondary. Figure64:24 Active/Active Clustering configuration can include configuring Virtual Group IDs and redundant ports. now display Logged Into: Backup SonicWALL Status: (green ball) Active page are performed on the Primary unit and then are automatically synchronized to the Backup. Active/Standby High Availability Monitoring, The Primary and Secondary IP addresses configured on this page are used for multiple, 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 Secondary/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. 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. 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. For best practice, use the same set of interfaces on each unit in each node. Note In a High Availability deployment without Internet connectivity, you must apply the license keyset to both of the appliances in the HA pair. Optionally, for port redundancy with Active/Active DPI, physically connect a second Active/Active DPI Interface between the two appliances in each HA pair. 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. Click OK in the confirmation dialog box. The generated packets are sent to the active firewall over the Active/Active DPI Interface, and are sent out from the active firewall as if the processing occurred on the active firewall. Step 6 Repeat this procedure for the other appliance in the HA Pair. (This is the setup shown in the diagram). For more information about physically connecting redundant ports and redundant switches, see the Active/Active Clustering Full Mesh Deployment Technote. Connecting the LAN and WAN Interfaces in a High Availability Deployment. Check " Enable Stateful Synchronization ". Active/Standby and Active/Active DPI Prerequisites. The two appliances in each HA pair must also be associated as HA Primary and HA Secondary on MySonicWALL. This section describes several methods of verifying the correct configuration of Active/Active Clustering and Active/Active DPI. Benefits of Active/Active Clustering Full Mesh. SonicWall University is the place to view our certification course catalog, the ATP class schedule, and activate e-learning keys for online modules. On each of the Active firewalls in the Cluster Node, disconnect the X0 cable while X2 is connected. The Enable Stateful Synchronization option is automatically enabled for Active/Active DPI Clustering. High Availability related log events can be viewed in the Log > View page. In the lower section of the page, shown below, the High Availability Status table displays the HA settings and status for each node in the cluster. This log may be viewed in the SonicOS management interface or it may be automatically sent to the administrators email address. Turn on all the other firewalls. veeam . SVRRP management messages are initiated on the Master Node, and monitoring information is communicated from every appliance in the cluster. Search for Windows Firewall, and click to open it. To connect the Active/Active DPI Interfaces for Active/Active DPI: 1. 7. 5. IPv6 High Availability (HA) Monitoring is implemented as an extension of HA Monitoring in IPv4. 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. Now we can test for no single point of failure on all devices and links with the following steps: 1. Example: Active/Active Clustering Two-Unit Deployment. Note that non-management traffic is ignored if it is sent to one of these IP addresses. Link Failures: Traffic should continue to flow in each of the following link failures: a. If a link fails or a port is disconnected on the active unit, the standby unit in the HA pair will become active. accessing a site on the public Internet note that the Backup SonicWALL, when Active, assumes the complete identity of the Primary, including its IP addresses and Ethernet MAC addresses. License Synchronization with SonicWALL License Manager, HA Synchronize Settings (syncs settings to the HA peer within the node), HA Synchronize Firmware (syncs firmware to the HA peer within the node), Authentication tests (such as test LDAP, test RADIUS, test Authentication Agent). The old site has a Sonicwall and the site has a Fortigate 60E. When finished with all High Availability configuration, click, Active/Active High Availability Monitoring, The configuration tasks on the High Availability > Monitoring page are performed on the Primary. Click Device in the top navigation menu. 3. However, such a setup has the following limitations: Failover will not be stateful and existing connections will need to be re-built. When viewing the Multi-Core Monitor on an active unit in the cluster, all firewalls in the cluster are displayed. 4. Note that non-management traffic is ignored if it is sent to one of these IP addresses. When Active/Active DPI is enabled on a Stateful HA pair, you can observe a change in CPU The same interface can have multiple virtual IP addresses, one for each Virtual Group that is configured. Click High Availability | Base Setup. Connect all the HA links of all the firewalls into a port-based-VLAN on Switch E. 2. In the setup described above, we also use Active/Active DPI along with Active/Active Clustering. After enabling Active/Active DPI, the connected interface will have a Zone assignment of HA Data-Link. Each Virtual Group has one Cluster Node acting as the owner and one or more Cluster Nodes acting as standby. You can view the CPU utilization on the Multi-Core Monitor. Note that this does not indicate that all the processing was performed on the active unit. On the Systems > Licenses page under Manage Security Services Online, verify the services listed in the Security Services Summary table. b.Connect X7 of CN1-Primary to X7 of CN1-Backup with a Cross-over cable. The SonicWALL Virtual Router Redundancy Protocol (SVRRP) uses this HA port connection to send Cluster Node management and monitoring state messages. In a two-unit cluster, HA pairs are not used. Settings On the to each unit independently for management purposes. 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. You can view system licenses on the System > Licenses page of the management interface. If both can successfully ping the target, no failover occurs. SVRRP management messages are initiated on the Master Node, and monitoring information is communicated from every appliance in the cluster.
