[c-nsp] eigrp question

[Kern, Tom]

I'm trying to set up an internet redudancy plan. i have 3 sites all connected via T1's. each site has its own internet connection(frame relay) and i'd like to set it up so if one site's firewall(sonicwall and watchguard) go down or the internet link goes down, internet traffic will automagically be rerouted via one of the other site's internet connection.
i'm avoiding bgp because i have no experince with it.
all my routers run eigrp. i thought using "ip default-network" would work. but if eigrp neighbors need to be on the same subnet, this won't help me. also eigrp would only work if the whole router went down(rare). i want the routes to change if the serial link is down.

does anyone know of a way to make this work? is it possible?
thanks

No. (I would be very interested in this if it could work). So far the
only thing I got to route across a firewall is either a tunnel (which
defeats having a firewall) or BGP.
