How To Enable Diablo III Port Forwarding

The basic process for forwarding your ports, whether for Diablo III or any other game, is simple enough. You need to go into the settings on your router, and tell it to forward the relevant ports.

To do that, though, you’ll need a few extra pieces of information. So before we begin, find and make a note of the following:

  • The IP address of your router.
  • The IP address of your PC or console.
  • The ports that Diablo III uses, and that you want to forward. Those are in the list above.

If you don’t have this information, and don’t know how to find it, fear not. We’ve made a guide, How to Forward Ports on your Router for Online Games, which will show you how to find them. It will also show you how to forward your ports for loads of games, not just Diablo III.

The process for forwarding a port is generally:

  • Get up a web browser window on your PC or console.
  • In the address bar, paste or type the address of your router.
  • This will take you to the router’s settings. Have a look around, and you should see ‘port forwarding’ somewhere. Click on that.
  • On the next screen, you’ll need to enter various details, so go ahead and paste your PC or console’s IP address into the correct box.
  • Next it will ask you for the ports you want to forward for Diablo III. Those are in the list above.
  • After you restart your router, your ports will be forwarded. Well done, that’s it.
