How to Port Forward Diablo II

Diablo II is an Action, Role-Playing, and Hack & Slash game published by Blizzard released in 2000.

Diablo II includes the following styles of gameplay.

  • Action games are fast paced and tend to put the player in the middle of the action, requiring you to jump over obstacles, climb ladders, and shoot things.
  • Role-Playing Games give you hours on end of game play where you can explore a new world through the eyes of your own character. They tend to be the longest style of game with the most immersive story lines. Popular RPG titles include Skyrim, World of Warcraft, and Fallout.
  • In a hack-and-slash style of game you spend most of the time just killing wave after wave of creatures. They are strongly emphasize combat over anything else. Hack-and-slash style games are usually also considered action games.

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 on occasion 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 router.
  • Your gaming machine's IP address.
  • A list of TCP and UDP ports to forward.

How to navigate to your router's IP Address

The easiest way to find your router's IP address is to run our free Router Detector utility. It's a part of the Network Utilities suite of tools and it's completely free to use.

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:

  • Start by logging in to your router.
  • Find your routers port forwarding section.
  • Put the IP address of your computer or gaming console in the applicable box in your router.
  • Put the TCP and UDP ports for your game in the corresponding boxes in your router.
  • Intermittently you have to reboot your router for the changes to take effect.
