WAN Reservation
On the Connections Setup / WAN Reservation 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 100. The Connections Setup / WAN Reservation page.
To activate the backup function, create several WAN connections. After that go to the
Connections Setup / WAN Reservation page, move the Enable switch to the right.
