Firewalls and routers are designed specifically to control your computer's incoming and outgoing connections. You may need to set up these security features to allow access to the game servers. If these are not set up correctly, the firewall or router may prevent you from connecting to World of Warcraft.

Blizzard does not offer direct support for proxies (Internet connection sharing), firewalls, or routers. The settings provided are suggested settings only. 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.

Here are some common questions and answers regarding proxies, firewalls, and routers.

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.

World of Warcraft uses the TCP protocol on ports 3724, 1119, 4000, 6112, 6113 and 6114.
The World of Warcraft Voice Chat feature uses the UDP protocol on port 3724.

How are ports restricted when using a proxy, firewall, or router?

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.

How do I configure my Operating System firewall?

Windows XP and Mac OS X ship with firewall services built into the operating system. While these services are disabled by default, if you have turned these services on, you may need to configure these services to allow the game to access the Internet.

Windows XP:

1. Click on the Start button.
2. Right click on My Network Places.
3. Select Properties from the list.
4. Right click on the icon for your Internet connection.
5. Select Properties from the list.
6. Click on the Advanced tab.
7. Click on the Settings button.
8. Click on the Add Button.
9. Type in WoW as the Description of service.
10. Type in your computer's name or IP address in the field provided.

Some firewall programs have preset ports available in their configurations that are often necessary to be open. One in particular is a connection to your DNS server. This usually takes place on UDP port 53. Please go to our Networking Help page for more information on how to open the appropriate ports for your proxy or firewall.

What do I do if I am still having problems connecting using a firewall, router, or proxy?
