Re: Failover internet connections, and implementation...

[Larry Offley <lucullus () shaw ca>]

You should also be able to setup the second connection and use both at 
the same time. Then If either of them is having a problem the traffic 
will use the other one. Look into a device capable of load balancing two 
connections. Then you are not "wasting" any equipment as it is actually 
being used to increase your bandwidth.
