Port Information for Firewalls, Proxies, and Routers

Who should I contact regarding the configuration of my firewall, proxy, or router?
Blizzard does not support proxies (Internet connection sharing), firewalls, or routers. The settings provided are suggested settings only. However, we do have some suggested settings for BlackICE, ZoneAlarm® Pro, Sygate Personal Firewall Pro, and Windows XP's Internet Connection Firewall.

You may need to contact your ISP or network administrator for assistance if you have opened the correct ports but still cannot connect or get others connected to you.

What do I need to know about ports?
Anytime your computer receives incoming data, it is sent to a "port". Your computer has many ports that can receive data, and different activities will utilize different ports.

How are ports being restricted?
Most proxy servers, firewalls, and other Internet connection sharing methods can restrict port access. Your configuration may be restricting packets from "unknown sources". In this case an "unknown source" would be defined as any IP address that you have not initiated the contact with. Once you contact the IP address, your proxy and/or firewall considers it "safe", or a "known source", since you initiated the contact. When you create a game on Battle.net, other users need to be able to contact you in order to join. In other words, they need to be able to initiate the contact. This becomes the real problem if your connection is restricting them from contacting you.

What ports are required and with what settings?
In order to connect to Battle.net, through your Local Area Network, while allowing others to connect to games you create, make sure you have the following ports setup as described below.

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)


(This information was taken from blizzard.com support) Hopefully that may help.

You can try the following, this is how you can reset your server list. I don't know if this will work but worth a try.

Reset the Battle.net server list:
Download our Battle.net server list fix to reset your Battle.net gateways to their default values. Unzip the downloaded file, and merge the information into your registery by double clicking on the extracted file. Many 3rd party programs will modify your server list, and should be removed or they will continue to cause connection problems with your game.

Download:

Deleting the Battle.net registry folders:
Click on Start then choose Run.
In the Run box, type the word "regedit" (without the quotes) and press OK. This will launch the Registry Editor.
Click on the + icon beside the "HKey_Local_Machine" folder. Some folders will appear underneath it. One should be called "Software".
Click on the + icon beside the "Software" folder.
In the folders that appear under "Software", Select the "Battle.net" folder and delete it.
Click on the - icon beside the "HKey_Local_Machine" folder. This will collapse the folders underneath it.
Click on the + icon beside the "HKey_Current_User" folder.
Under that, click on the + icon beside the "Software" folder.
In the folders that appear under "Software", Select the "Battle.net" folder and delete it.
Click on the - icon beside the "HKey_Current_User" folder to collapse it as well.
Now that both "Battle.net" folders are gone, close the Registry Editor, restart the game, and try your Battle.net connection again.

Checking the Hosts file:
Click on Start then Search or Find files and folders to search your hard drive for a specific file.
In the file name field, type the word "hosts" (without the quotes) and search for that file.
Once Windows has found this file, you may want to make a backup copy and name it hosts.bak.
Double-click the hosts file (not the backup) and choose to open it using Notepad.
The term ".battle.net" should not appear anywhere in this document.
If you see any ".battle.net" entries, please delete them.
Close the Notepad document and choose Yes when it asks you if you want to save the file.
Now start the game and connect to Battle.net.
