When you play Diablo II you will experience the following styles of play.

Port Forward Diablo II
When you are playing Diablo II 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 intermittently 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:
- The IP address of your network router.
- The IP address of the device that the game will play on: either your computer or your console.
- A list of TCP and UDP ports that need to be forwarded.
