Getting two PCs on the ‘Net

We have two PCs running Windows 2000 connected to a switch. We connect the broadband link to the same switch, but we can only have one computer connected to the Internet, and cannot use Windows networking to communicate with the other PC. The ISP allows for only one IP address to be allocated dynamically from its Dynamic Host Configuration Protocol server. Either PC can be connected, as long as we first release the IP address.

Is there a different way of solving this problem? We’ve thought about forcing both computers to use the same media access control address, but don’t know what the consequences would be.

The solution is not duplicating the MAC addresses.

Hide your LAN behind a gateway that provides network address translation (NAT) and routing services for your LAN’s Internet connection. It’s possible to configure Routing and Remote Access Services on one of the Windows 2000 PCs to provide these services for the other PC using Internet Connection Sharing or NAT.

See Demand-Dial Routing and Router-to-Router VPNs in Windows 2000 for instructions. It would be easier to buy a small broadband router to place between your switch and the ISP connection.
