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.

I've a question about failover internet connections. I'm interesting in knowing what kind of implementations that other SMB's use for redundancy,and to switch to in the case of a DOS attack.Do any of you have redundant highspeed internet connections for your offices (versus those for datacenters)? If so, what kind of setup do you have? Here's the setups I'm considering... 1. Have a second cable modem/dsl modem active, but not hooked into the network. In the event of a failure, move the connection for perimeter devices over to the standby connection and reconfigure the perimeter device to use a different IP. 2. Have a second set of perimeter devices (firewalls) programmed to use the IP's on the second connection, as a hot standby. My problem with the first option is the time it would take to reconfigure firewalls and IDS' to use the other ISP's connection. The problem I have with the second is the expense of firewalls and IDS' just sitting thereidle.Any input is greatly appreciated!Dan
