Also the computer behind the "middle man" has to either have his own IP address, or the "middle man" has to do address translation for him. To have both computers "live" on the Internet, your ISP should have given you two IP addresses. If you don't have unique IP's for each one, the "middle man" will have to assign an address to the other computer and translate addresses -- serve as a NAT router. If you use XP's Internet Connection Sharing, it's going to do this for you. It's possibly the quickest way home for you. But NAT is the big reason why others have suggested the "4-port router" option. Erik
