Here's what I've done: Port forward the following, if they were already forwarded, no need to mess with them. 4000-4005 7234 10000 Configure your server data to use the "7234" port instead of 4000\. Go to IPChicken, or WhatismyIP, and get your IP Address. Config your game client's IP to Your IP, and the port to 7234\. If this doesn't work, try the other ports you've opened, saving 4000 for the last resort.
