Frame Relay and NT4.0 installation

Are your NT4 server and the workstations and the routers Ethernet interface all on the same subnet and physical segment? It sounds like "not". Check "ipconfig /all | more" on the server and a couple of wkstns and see what IP addresses come up.

Isit that your NT4 server has 2 NICs, one on the subnet that has your router, and one on the subnet with your workstations. Assuming so, and assuming that you really do need to do it this way, then you need to enable routing ("IP Forwarding" in Micro$oft-ese) in the Network Control Panel.

If you can access Internet from at least one machine it means that your router and hub is working properly. Make sure you check IP addresses on our Server and on your Workstations that it is in the same network subnet. How did you select IP address on your server? Do you have Network Address Translation in your router?

As you mentioned DHCP, it mean you should create Scope of Valid IP addresses and configure additional IP Information. Then check that your workstations pick up address and IPsettings (especially Subnet Mask and Default Gateway).

Good luck.

If your machines are using the private ip range then they will not get passed to the internet. If the internal interface of the Cisco is say 192.168.1.1 and the external is say 216.xxx.xxx.xxx then when your clients try to get to the inet they won't get passed to the next site. You will need NAT or give your machines real IP's.

Also you might try the ROUTE ADD command on the server.
