Fallback WAN Connections (Failover)

If your router model supports different connection types then you can
configure multiple connections (max. one of each type) which will then be
used as backup connections when the primary connection is unavailable, thus increasing the
availability of your machine. The fallback connection must be on a different network than the
primary connection.
How does it work?
The router constantly checks each configured connection to determine whether the
connection is available or not. This is done by sending a keep alive message to a public IP
address every couple of seconds. This keep alive message needs to fail several consecutive
times for the connection to be considered unavailable. The same goes for it to be considered
available again.
When the preferred connection is unavailable, the router will automatically switch to
its fallback connection. When the higher priority connection is back up, the router will
automatically switch back to that connection.
To set it up
1. In the Fleet Manager menu, select Devices
2. Expand the Network
3. Set up multiple WAN connections, following the steps on pages 2-17 through 2-19.
4. When multiple WAN connection types are configured, the router will automatically use
one as the preferred connection and others as fallback connections.
5. To change the priority of the connections, you can drag and drop
arrange their priority.
6. You can edit each connection's tracking settings
interval used to check if the connection is available or not. We recommend leaving the
default values untouched for the best results. If you do need to change the settings, the
router will periodically check up to four public IP addresses to determine that the
preferred WAN connection is available. The default IP addresses to track are public DNS
servers. Any public IP address may be entered, but should be an address that is always on
and will respond to ping requests. The default tracking interval is 5 seconds. The interval
can be adjusted between 1 and 60 seconds.
