Amy, I think you need to configure your Gateway of Last Resort to be the new router IP 10.0.0.97 in both routers 100.0.0.1 and 200.0.0.1. HTH.

Now I need to change the Internet gateway from the server to another router on the network. I was apparently smarter back when I first configured these routers but having not configured a router since, I can't seem to get it to work. The computers at the end of this DSL line have access to the server but not the Internet. The routers are 3COM 840's but as I recall they take pretty much the same commands as any router. I'll attempt a little diagram: 100.0.0.1 Router at back of plant 200.0.0.1 -------> 200.0.0.2 3COM Router in server room 10.0.0.7 ----> Switch ----Server 10.0.0.80 --- Cisco Router 10.0.0.97 The 200.0.0.1 - 200.0.0.2 part is the actual DSL connection internal the routers. The Cisco router is going to send them out to the Internet. The server has data and apps that they also need access to. The clients need access to both.
