Battle.net Router Ports

[ChrisH36]

Many people nowadays are now getting Routers to start a LAN network in your house and so all PCs/Laptops in teh house can connect to the Internet without having to buy more modems. However, you need to configure this router to handle the delivery of information. This is a list for all the BLizzard games and the ports they will need.

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’ve changed the default port in the Options/Gameplay screen)

World of Warcraft:
Allow port 3724 TCP out
Allow port 3724 TCP in

For my DI-524 Router I have this:

Battle.net - 3724 (for WoW), 4000 (for Diablo II),6112-6119 using TCP/UDP

Make sure you test your ports so that they work. You can retrieve most port information from technical support sites for the company, contacting the people or searching other forums. This sticky should help cut the port problems up.

Accessing the editing information of your ports and such can be done via by your router's menu. To access this, it depends on who made it.
