DELL SonicWALL HA Configuration Resources


Active/Standby HA allows two identical firewalls running SonicOS to be configured to provide a reliable, continuous connection to the public Internet. One firewall is configured as the Primary unit, and an identical firewall is configured as the Secondary unit. In the event of the failure of the Primary firewall, the Secondary firewall takes over to secure a reliable connection between the protected network and the Internet. Two appliances configured in this way are also known as a High Availability Pair (HA Pair).

Basic Active/Standby HA provides stateless high availability. After a failover to the Secondary appliance, all the pre-existing network connections must be re-established, including the VPN tunnels that must be re-negotiated. In Stateful High Availability, the network connections and VPN tunnel information is continuously synchronized between the two units so that the Secondary can seamlessly assume all network responsibilities if the Primary appliance fails, with no interruptions to existing network connections. Stateful High Availability is licensed.
