We have two routers one a Cisco 2621xl provided by us with an ATM connection with one provider. AT$T has a router there as a second T1 line. I would like to route traffic from two wirreless subnets 188.8.131.52/24 and 10.10.0.0/24 to the AT&T router. Both of these routers are plugegd directly into a Cisco 2950 switch as well as the wireless links providing connection to the above subnets. We are only using static routing (something I inherited) At present I have the gateway addresses for these two subnets set up on the FE ports of our Cisco 2621,being 10.2.15.1 and 10.10.0.1, My question is can I just get AT&T (managed router) to assign 10.1.0.1 and 10.2.15.1 to their FE ports on their router and me change mine to another ip address,and make this work?
