3.4 Features with Multiple WAN Links
This router supports multiple WAN links. This allows you to take advantage of
failover and load balancing features to ensure certain intern et dependent services are
prioritized in the event of unstable WAN connectivity on one of the ports.
Setup > Internet Settings > WAN Mode
To use Auto Failover or Load Balancing, WAN link failure detection must be
configured. This involves accessing DNS servers on the internet or ping to an internet
address (user defined). If required, you can configure the number of retry attempts
when the link seems to be disconnected or the threshold of failures that determines if
a WAN port is down.
3.4.1 Auto Failover
In this case one of your WAN ports is assigned as the primary internet link for all
internet traffic. The secondary WAN port is used for redundancy in case the primary
link goes down for any reason. Both WAN ports (primary and secondary) must be
configured to connect to the respective ISP‘s before enabling this feature. The
secondary WAN port will remain unconnected until a failure is detected on the
primary link (either port can be assigned as the primary). In the event of a failure on
the primary port, all internet traffic will be rolled over to the backup port. When
configured in Auto Failover mode, the link status of the primary WAN port is
checked at regular intervals as defined by the failure detection settings.
Note that both WAN1 and WAN2 can be configured as the primary internet link.
