Note: The DIR-455 supports several kinds of WAN interfaces, allowing you to assign
either a WAN or a WWAN(3.5G) connection as the Backup WAN. If the Primary
WAN is down or unavailable, configure the Backup WAN to Enable, and all the
traffic will be routed through Backup WAN. This feature is called WAN Failover.
You can use WAN Failover if you need redundancy to your Internet connection or
any other network.
