This brings me to the dilemma that if I set this up, and the t1 goes down, but the lan link is still active (lets say something breaks on the ISP's end 5 hops down the line) then there will never be a fail-over. My questions is, if a link is never broken, aka the link light never goes out, how would the ASA ever know to fail over or use the higher rated default gateway? My concept is that this is a link-state fail-over and not something more sophisticated. I read it and it looks like it would work. I found this article that states that it "can". My question is, can the ASA 5505 perform a Active/Passive Dual WAN hookup? We are looking to get a 4g/WiMax modem/router in the building for backup internet. This t1 has gone down from time to time due to bad weather. They have a t1 hooked up to it and it works fine. What I have is a client with a Cisco ASA 5505. I am hoping to find a solid answer to this question.
