Reservation WAN
On the Net / Reservation WAN 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 113. The Net / Reservation WAN page.
To activate the backup function, on the Net / WAN page, create the main and the reserve WAN
connections. After that proceed to the Net / Reservation WAN page, select the Enable
reservation checkbox, and specify the needed values in the fields displayed on the page.
