My network consists of two different networks shared by a linksys router(both W2K servers). Network A and network B respectively. Network A as well as all the clients can access the internet. On network B the server has two NIC cards installed. One NIC card attached to the Linksys router. Server B is acting as a router for network B. The second NIC card is attached too a switch to give the client computers on Network B access to the Internet. Now, the Server with the direct connection to the Linksys router can access the internet, but the client computers can not. All the client computers can ping each other on network B including the Linksys router. I have installed Wingate on the Server B router and that allowed all clients machines to access the internet, but for training purposes Wingate defeats the purpose for network B. I am trying to do what Wingate does without the use of Wingate. Suggestions?
