Connection problem PLZ HELP!

you need to be a little router savvy to make it work. First you need to know the local ip of your computer you want to play on. At command prompt type ipconfig . Once you know the computers IP (assigned by your router) there is a couple things you can do. You must get into your router settings via the web interface. In the router settings it is easiest to find the DMZ feature. Use the DMZ feature and enter the IP of your gaming computer. This opens up all ports to your computer. It is less secure that way so get in the habit of turning off the DMZ feature as soon as you finish playing. There is a more secure way to make the game work also. It involves passing ONLY the specific ports that the game itself utilizes. It can be more of a hassle to do it that way. Just try DMZ first as an easy way to know if your router is the real problem why you can't join games. It should work.
