Problem configuring 1710 access router

I'm having trouble configuring a recently installed cisco 1710 access router, any help would be apprecated. My set-up is as follows. A dsl router connected to the internet on one side and network 192.8.200.0 on the other. The Cisco 1710 is connected to 192.8.200.0 on the ethernet port and network 192.9.200.0 on the fastethernet port. Most all of my computers are on the 192.9.200.0 network.

I can ping both ports on the 1710 from the 192.9.200.0 network. I can also ping the 192.8.200.0 port of the DSL router from the 192.9.200.0 network. I can ping/access the internet from computers on the 192.8.200.0 network through the dsl router, but cannot access/ping the internet from the 192.9.200.0 network.

I think the problem is that the Cisco 1710 is not sending/forwarding non 192.8.200.0 requestes from the 192.9.200.0 network to the dsl router port.

I'm sure I misunderstading the routign concept for the 1710.

Any ideas?

Doug,

Were both of those class c address spaces actually assigned to you by your ISP? As long as your 1710 has a default route in the forwarding table, it should send your packets to the DSL router, regardless of whether the source is the .9 or .8 network. So check to see that you have that in place ('ip route 0.0.0.0 0.0.0.0 x.x.x.x' where x.x.x.x is the ip of the DSL router) and then make sure that your ISP has routes to both networks. All of this assumes you are only using static routes. If you are running any kind of routing protocol, things change a little.
