Our company is using a Cisco 1841 router, and a Watchguard Firewall. We have a T1 line that connects to the Cisco 1841, and then the router is connected to the External interface of the firewall. The router config is very basic, just a default route...NAT is done in the firewall.
Due to ongoing issues with reliability of the local loop wiring, we are getting a second T1 line from a different (wireless) ISP. The wireless T1 is an ethernet connection, so it can be hooked up to an ethernet interface on the router.
My question is how can I set everything up for failover...so if the main T1 goes down, everything gets routed in/out the second T1 line.
Basically, I'm pretty confused about how all this will work, so any advice would be greatly appreciated.
Thanks!
