First you need to nic's in your connection sharing computer. One connected to the DSL modem, the other connected to your hub. The nic connected to the DSL will be your WAN connection, and the nic connected to your hub will be your LAN connection.To implement this setup with windows, you will need to install ICS for your new configuration. Simply remove ICS and reinstall it. If you have a variety of windows OS's on your LAN, it will be easier to setup manually than to use the client disk. Enter the tcp/ip properties page and enter the information for your network; ie. gateway: 192.168.0.1, primary dns: 216.88.54.2, secondary dns: 223.255.0.2. Your dns server information can easily be acquired by running winipcfg (win9x-me); ipconfig /all (nt-xp).
You will find that this is very similar to the configuration you are already familiar with for a dial-up ICS network.
