3-4 Fail Over

WAN failure detection works by detecting the presence of traffic on the 3G modem link. If

the link is idle for too long the router will attempt to ping a target IP address. If the ping

does not reply, the router assumes the link is down and attempts to fail over to ethernet

WAN link.

Here are descriptions of every setup items:

connection. If the major Internet connection is idle for this amount

of time then the router will send a ping to the target IP Address

you have assigned. If the ping gets a reply, the router will restart

the idle timer, otherwise it will failover to the second priority of

WAN connection.

Note: The router will not connect back to the first priority of Internet connection

once it has already failed over to another one.
