Failover through Route Policy

Through route policies, both WAN interfaces can be active but only one will be in use, with the other ready to route traffic if the main connection drops.

In this example, WAN1 is the main connection and WAN2 is the backup connection, which could be sitting idle or utilised through additional route policies, for instance maybe VoIP calls route through WAN2.

Normally, traffic will be routed through WAN1 with this Route Policy setting. If WAN1 drops, the route policy will switch to the backup Interface. Traffic will only be routed out via WAN2 if the WAN1 connection isn't available.

Follow the setup guide below:

-Navigate to [Routing] > [Load-Balance/Route Policy]

-Open any available index for configuration (In this example we'll use Index 1) and configure it like in the image below:

• • The "Failover To" setting defines the connection that's used to back up the Internet connection. In this example, WAN2 is the backup connection.
  • The "Failback" setting defines how quickly connections are moved back to the main connection when it's restored. When ticked, all sessions going through WAN2 are dropped when WAN1 reconnects, so that clients can resume using the WAN1 interface.
