Watchdog
On the Net / Watchdog 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 68. The Net / Watchdog page.
To activate the backup function, on the Net / WAN page, create the main WAN connection and
enable it (select the Enable checkbox on the page for creating the connection). Then create the
reserve WAN connection and disable it (deselect the Enable checkbox on the page for creating the
connection). After that proceed to the Net / Watchdog page, select the Enable checkbox and
specify the needed values in the fields displayed on the page.
