To setup port forwarding on this router your computer needs to have a static ip address. Take a look at our Static IP Address guide to setup a static ip address. When you are finished setting up a static ip address, please come back to this page and enter the ip address you setup in the Static IP Address box below.
Open a web browser like internet explorer or Netscape. Enter the ip address of your router in the address bar of your browser. In the picture above the address bar has http://www.google.com in it. Just replace all of that with the ip address of your router. By default the ip address should be set to 192.168.1.1.
You should see a box prompting you for your username and password. Enter your username and password now. By default both the username and password are blank. Click the Ok button to log in to your router.
We will list a series of lines here that will show you exactly how to forward the ports you need to forward. Half Life 2 Steam Server requires you to forward the 27015,27020 ports. Go ahead and enter the settings shown above into the Open Ports Setup menu and then click Ok.
You should see another page of settings that need to be entered into one of the blank lines on your routers Open Ports Setup page. Go ahead and enter those settings and then click Ok.
When you're finished, click Ok near the bottom of the screen to save your changes. And that's it! You're done!
