Second, I am going to assume that you are trying to use Internet Connection Sharing (ICS). Even if your upstream provider is using a private address, ICS should still work. ICS allows you to connect your LAN to the Internet through your ISP. All that is needed is that the server be powered-up, that is connected to the modem, and that your client machines are configured to use DHCP.
Generally, the steps to configure ICS are as follows
- Log onto the Server as administrator or you need to be a member of the administrators group.
- Open Network and Dialup Connections
- Click on the sharing tab
- Verify the ICS check box is selected
- Click on the Applications tab if you wish to configure any specific applications
- Configure the clients
After ICS is configured your users should be able to e-mail, FTP, or use Explorer just as if they were already connected to the ISP.
There are several good sites that detail this setup step-by-step. Surf over to www.practicallynetworked.com/sharing/sharing.html for step-by-step screen shots.
