Help: Hosting Warcraft 3 B.net Games

I am having issues with hosting my Warcraft III: TFT game over B.net. I've gone into my firewall and configured the system to allow router ports through the firewall from 6112-6118, but still no luck. In the game options I have it set to host through 6112 so I have no idea why it is not working. Can anyone help?

I've tried doing that, however the ports I opened I used my computer's name, and the internal ip address isn't working either. I may need to reconfigure my router since this computer is over a LAN.
