Clip from http://www.microsoft.com/windowsxp/using/networking/expert/northrup_03may16.mspx:

"If you use a router to connect to the Internet, you probably need to configure it to allow the Remote Desktop connection to your computer. For more information on routers and firewalls, see my Internet Firewalls column. You need to forward two ports to your Windows XP Professional-based computer: TCP port 3389, which Remote Desktop requires, and the port you specified in the TCP Port field in Internet Information Services (or TCP port 80 if you did not change the default). If you use Internet Connection Firewall (and you should!), see How to Manually Open Ports in Internet Connection Firewall in Windows XP for instructions on allowing traffic by TCP port."

To be more help, are you looking to connect to the persons home computer from the office, or the office computer from home?  If you're looking to get to the home computer, he needs to open up the ports on his home computers firewall or router.  If you're looking to get into the office computer from home, and the office computer doesn't have its own public IP (it uses the Windows 2000 server, or a router, for instance), you'll need to setup port forwarding on that router.  Note that there are serious security issues to consider before doing this.

I appreciate the accept, but I'm not sure it's valid.  If your true question is how to configure the port forwarding, I would ask it as such, as I thought you were just asking for the ports you needed to forward.  You should get a mod from the EE community area to reopen this question so that others that may have the answer can see it and perhaps know.

But, my short answer would be that you'd need to login to the admin interface to setup the forward.  This is sometimes a web front end, and sometimes will be a telnet / hyperterminal solution.
