Well, it's a little hard to help you because we don't know what your firewall/router IP is. However, you could find out if you knew your computer's IP address (The utility JazzForce will tell you), and by changing the last digit to a 1. Then, type that IP address into your browser's address bar. It will ask you for a username and password (Usually both are set to "admin" without the quotes). After that, you go to the page which lets you open/forward ports. You must put in ports ranged 10052 to 10054 on both TCP and UDP, to your computer's IP. That should be all.
