How to Port Forward Warcraft III on the Arris TM501b

Having trouble forwarding ports on the Arris TM501b?

If you are having trouble with this guide, then perhaps PFConfig may be your solution. PFConfig is a software tool that will automatically forward ports for your router to save you time and hassle.

We are going to show you how to forward port 6112 TCP, which is the only port that must be forwarded for Warcraft III. You can change the port that Warcraft III uses for hosting on the Options/Gameplay screen. If you decide to change the port that Warcraft III is uses for hosting you should select a port in the 6113-6119 range. You would really only want to do this when you had two computers on your network that were trying to host custom games. Remember that you would need to forward the port that the second computer will be hosting on to the second computer.
