我想:你是希望两台电脑用一个DSL MODEN (given by bell sympatico) 同时上网吧?
you need:
1)hardware setup.
In simple word,you need one of your PC to become a gateway server by adding an additional NIC card to it, and connect your second PC to the gateway server ( second NIC card ) with an cross-over cable if you don't have a hub.
2)network setup.
a.make sure you can sign onto the internet using gateway server
b.make sure the gateway server can talk with your second server(CMDing) using the second NIC cards
c.share the internet NIC card, and make a bridge.
