On the Connections Setup / WAN Failover page, you can enable the WAN backup function,
which provides you with uninterrupted access to the Internet. When your main connection breaks
down, the router activates the backup connection; and when the main channel is recovered, the
router switches to it and disconnects the reserve one.
Figure 106. The Connections Setup / WAN Failover page.
To   activate   the   backup   function,   create   several   WAN   connections.   After   that   go   to   the
Connections Setup / WAN Failover page, move the Enable switch to the right.
