2 WAN interfaces on a cisco 2811. Nat routing, route-map, and other issues.

I added a 3 MB SDSL connection to my Cisco 2811 Integrated Serices router, and now all of the routing for NAT mapping (hosted on the T1) are hosed as the default gateway switched to the DSL.

I have tried route-maps, but nothing seems to work and a tracert to google from the IP addresses who's traffic should be going out the T1 shows that the traffic is indeed going out the DSL.

As I spend 8 hours yesterday working on this and got no where , I would appreciate your help

Also, as I have worked and reworked my configuration until I'm sick of looking at it, I would prefer a "try this approach using these commands" than a "show my your configuration and I'll tell you what's wrong with it."

Taking the time to change all of my IP addresses and host names to protect the company is not something I wish to do at this point.

Thanks for your help!

Can you leave us some kind of drawing with your layout as well as a show ip routes (that's a beginning).

Before suggesting to try something, we need to understand better your topology :-)

I believe the last command that I needed was the "ip policy route-map." All the rest I had.

What is the purpose, if you don't mind telling, of the

route-map whichwayout permit 30
set default interface Null0

set of statements

r0ssc0

route-map whichwayout permit 30
set default interface Null0

All traffic going through that interface is subject to the route map. If it does not match any of the previous statements the packet will not be routed using the routing table. So you add in the last statement to catch all and bring the standard routing table back into play.
