Presumably this ties in with your other posting about using a WRT54G router in conjunction with a USB modem?

If you want to network the two computers to share the internet connection, connect them directly with a "crossover" ethernet cable and enable "Internet Connection Sharing" in the "host" PC.

To enable “Internet Connection Sharing” in Windows XP, open the Network Connections folder, right click the actual internet connection (modem connection), select Properties and then the Advanced tab. Tick the box “Allow other network users to connect through this computer’s Internet connection”.

When you enable “Internet Connection Sharing” on the Internet connection in the “host” PC, it automatically configures the Local Area Connection with the IP address and subnet mask The “client” PC’s Local Area Connection should be set to get its IP address automatically, which it does by DHCP from the “host”. Also, if you run the Zone Alarm firewall in your “host” PC, the Internet Zone Security level must be reduced from High to Medium or “ICS” traffic will be blocked.

If you are not intending to share an internet connection, you will need to allocate a fixed IP address to the "Local Area Connection" in each PC, using one of the ranges reserved for use in local area networks - most commonly a 192.168.x.x address with a Subnet Mask of

For example:

PC1 with subnet mask
PC2 with subnet mask
