Okay, when your friend can't connect, what does it say?
Does it say something like "trying to connect to server" and then finally "Could not connect to server" or something?
If that is the case, you will most likely have to port forward your router; http://portforward.com/
Find your router there and it will tell you how.
Ports 2302, 2303, and 80 need to be forwarded. (80 should be fine by default so don't worry about that.)
