Forward Ports for Half-Life 2
When you are playing Half-Life 2 you might need to forward some ports in your router. Forwarding ports is a useful trick in gaming because it can really help to make your network connection most stable and sometimes even faster. Routers were not designed to allow incoming network requests and some games can play tremendously better if an incoming connection is forwarded through the router to the game.
Before You Forward a Port
Before you can forward a port you need to know the following things:
- Your router's IP address.
- The IP address of the device that the game will play on: either your computer or your console.
- The TCP and UDP ports to forward.
How to locate your router's IP Address

How To Forward Ports
A smart way to forward your ports is to use Network Utilities. Since Network Utilities allows you to both forward and un-forward ports easily you can keep your network security maximized, and then forward ports only when you need them. Alternatively you can do it by hand.
The general process for forwarding a port is:
- Open a web browser and navigate to your router's IP address.
- Locate your routers port forwarding section.
- Put the IP address of your computer or gaming console in the correct box in your router.
- Put the TCP and UDP ports for your game in the corresponding boxes in your router.
- Sometimes you have to reboot your router for the changes to take effect.
