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 192.168.0.1.

Click the Advanced link near the left of the page.

You should now see a new menu. In this new menu, click Virtual Servers.

We will list a series of lines here that will show you exactly how to forward the ports you need to forward. Counter Strike requires you to forward the 1200,27000-27015,27020-27039 ports. Go ahead and enter the settings shown above into the Virtual Servers menu and then click Add as New Server.

You should see another page of settings that need to be entered into one of the blank lines on your routers Virtual Servers page. Go ahead and enter those settings and then click Add as New Server.
