I have Windows 2000 Advanced Server with 2 NICs as a gateway. It is plugged into my ethernet hub with the 2 windows xp pro computers. the other NIC is plugged into my dorm room ethernet port. The workgroup has to be GCC in order for the computers to interface properly with the rest of the college LAN. I have gotten internet connection sharing to work before, between just 2 windows xp pro computers with this type of setup, but now i'm looking for a more sophisticated solution. I am trying to setup my Windows 2000 advanced server machine as a NAT router. I would be satisfied with any solution that gives me internet connectivity on all 3 computers with the Windows 2000 Advanced Server machine as the gateway... thank you.
