I think you can solve part of your problem by using static routes or additional gateway entries on your routers. You would need to add a static route or additional gateway entry to the Netopia's routing table to point to the second Domain A (DSL) router. Depending upon how the Domain A DSL router is configured, it also may need a gateway or static route to Domain B. Then, you also need name resolution. Depending on how you are doing your name resolution currently, you can add static WINS entries on either side, use DNS or use a HOSTS file on your workstations. BTW, you could also solve this problem by setting your Netopia router to use NAT, change your Domain A IP addresses to match your Domain B scheme (use DHCP), and away you go! If you need additional help, don't hesitate to email me. Hope this helps!

You will need to add a default route to the Lucent router in Domain A pointing to the Internet Router. You will also need a route defined on the Lucent router located in Domain A pointing to the Lucent router in Domain B for the address schemes present in Domain B. Then define the Lucent router address in Domain A as the default gateway for all the workstations in Domain A. In Domain B, all workstations should have a default gateway of the Lucent router in Domain B. The default route for the Lucent router in Domain B should be the Lucent router in Domain A. DNS/WINS Name resolution should only be needed if you want to connect or ping using the NETBIOS names of the server or workstation. If you plan on only using the static IP addresses you should not need them. However, they will not show up in the Network Neighborhood without a WINS static entry and valid routes. Email me if you need anything else.

I agree with the previous posts in that you need to set up you routes between the two domains. There are a few ways to do this. The easiest would be to set up static routes between the two domains. What is the sevond router on Domain A for? is it a redundat internet link? A link to another domain and router? When you start to have multiple routers on the same domain it gets a bit more indepth. You can set you routers to be interconnected and use OSPF (open shortest path first) It really dependson what the routers are for. Also you need to make sure that both domains use the same WINS server or set up a WINS server in the B domain with a push/pull relationship to your WINS server in domain A. Routing is not something to be taken lightly hopefully with the additional posts here you will be alright but be careful.
