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.
To activate the backup function, create the main and the reserve WAN connections. After that go to
the Connections Setup / WAN Reservation page, move the Enable switch to the right, and
specify the needed values in the fields displayed on the page.
