Hello and welcome to our port forwarding guide.

1) General overview

What is port forwarding and why do you need it? Port forwarding (sometimes referred to as tunneling or virtual servers) is the act of forwarding a network port from one network node to another. Port forwarding allows remote computers (e.g. public machines on the Internet) to connect to a specific computer within a private LAN. So in order to host a game online, you must allow public computers on the internet to connect to your computer. If you don't port forward, all incoming connections to your PC will be refused and thus no one will be able to join your game.

2) Requirements

Open cmd.exe (Start > All programs > Accessories > Command Prompt) Type ipconfig, notice the Default Gateway.

NOTE: Enter Warcraft > Options > Game Play Check your Game Port, it should be 6112 on Normal Gateway and 6113 on GProxy Gateway.

3)Configuration

Open your web browser, type the IP you just saw, for example, in my case I have to type http://192.168.1.254

You should see a box prompting you for your username and password. Enter your password now. By default your username and password are admin.

You can find your router's username and password in your router's manual.

Click the Log in button to log in to your router.

Ok, Now you must search for "Port Forward", "Virtual Server" or "Game & Application Sharing". They are usually located in the advanced settings of your router.

Some routers have Warcraft 3 in their database, so all you have to do is add the Warcraft 3 to the Applied Rules. If you don't have the game, create a new application with the following settings

Protocol: Any      
Port Range: 6112
Translate To: 6112

Or if you don't have "Any" as a protocol type.

Protocol: TCP      
Port: 6112
Translate To: 6112


Protocol: UDP      
Port: 6112
Translate To: 6112

For portforwarding and port opening it is NOT required to have a range from 6112 to 6119 opened. The chance that you will have eight (8) games hosted is very, very small. - MusicDemon 07-Aug-2012
