Setting up networked PC’s to view each o

We are running a network NT4.0 server with 10 PC’s on a hub. Problem is we just got DSL service on the server and I can’t access any of the computer’s on the network through the router. If I disconnect the router and just put my hub on the server,then all is cool in OZ, but I’d like to be able to set it up where all PC’s go through the hub to the router and then the server so all PC’s will be able to get online and be seen on the network.

Note: I did notice that some IP addresses are different.

Any suggestions on resolving this issue would be greatly appreciated.
