Anybody know how to port forward with D-Link DI-704 Router?

I am having problem using "Update" command to get the internet servers list. Whenever I click "Update," the game would start getting the list but half way through the list, I would lose the internet connection and I would never get the list. After searching through internet, people said something about setting up port forwarding on the router. I looked throgh my D-Link router's setup program and I don't see anything about Port Forwarding. I was wondering if anyone out there with this router knows how to do Port Forwarding.
