WAN failover
The WAN failover page displays a summary of the configured WAN interfaces and their priorities (Metric). Lower metric values
determine higher priority. The priority of the interfaces can be adjusted using the up and down arrows in the Priority column. When
the interface with the highest priority goes down, the router fails over to the next highest priority interface. The method used to
determine whether an interface is
“up” or “down” is defined by the Monitor setting. By default, an interface is monitored by its link
status.
To access the WAN failover page, click on the Networking menu at the top of the screen then click on the WAN failover menu item
on the left.

To edit an interface, select the edit icon for the interface you wish to edit. The Failover configuration page is displayed. When
Monitoring method is set to Hardware link the failover is controlled by the physical detection of the link.

When Monitoring method is set to Ping, the router sends periodic ping requests to the specified addresses to verify the connection
is working. This works in a similar manner to the Watchdogs feature but with different ranges on the timers. Please refer to the
section of this user guide for a more detailed description of this function.
