If players are not able to join your game, you may have a firewall in place. Firewalls may prevent incoming networks from reaching your computer and prevent you from hosting games.

A firewall can come in many forms. In households, they may exist as security software, router and/or modem. The following information will help you configure your firewall.

Ports

Ports can be thought of as points of connection. The game listens to these ports to receive all of the information it needs to function. You will need the following ports opened to allow your game to accept connections and to host games:

Diablo and Warcraft II Battle.net Edition:
  • Allow port 6112-6119 TCP and UDP out and in

    Diablo II:
  • Allow port 6112 TCP out and allow established sessions in
  • Allow port 4000 TCP out (realm games)
  • Allow port 4000 TCP out and in (hosting open games only)

    StarCraft:
  • Allow port 6112 TCP and UDP out and in

    Warcraft III:
  • Allow port 6112 TCP out and allow established sessions in
  • Allow port 6112 TCP in (hosting custom games)
  • Allow port 6113-6119 TCP out and in (hosting custom games if you have changed the default port in the Options/Gameplay screen)

    World of Warcraft:
  • Allow port 3724 TCP out and in for Game
  • Allow port 3724 UDP out and in for Voice Chat

    Blizzard Downloader:
  • Allow port 6881-6999 TCP and UDP out and in

    Software Firewalls

    You may recognize names such as Norton Internet Security, McAfee Personal Firewall Plus/Express, ZoneAlarm, Sygate, Panda, and many others. These security programs act as firewalls that can block single programs or specific ports from the network. Here are some links to popular software firewalls that may help you:
