"My computer is behind a firewall or is connecting through a proxy server (for example, through a work, school, or public computer). What ports do I need to open to play MSN Games?
To resolve this issue, please follow the instructions below.
Open ports in a firewall or proxy server
Some games will not load if your computer system connects to the Internet through a firewall or proxy server unless certain TCP Ports are opened in the firewall or proxy server. Most work, school, and public computers are connected through a firewall or proxy server for security. If you have a cable or DSL modem, you may also have a firewall installed. To open these ports, consult the help files for your firewall software or contact your network administrator or IT technician for assistance. Ports that need to be opened to play MSN Games:
80 (To access MSN Games – required for all games.)
443 (To use your MSN Games account sign-in option.)
1863 (MSN Messenger Instant Messaging Program – only necessary for Invite a Friend game)
6891 and 6900 (MSN Messenger File Transfer features – only necessary if you wish to use these features in MSN Messenger.)
6667 (To use chat features in CD-ROM games and Classic Card and Board Games including Bridge, BridgeClub, Classic Backgammon, Checkers, Chess, Cribbage, Euchre, Go, Hearts, Reversi, Spades.)
28000-29100 (To access CD-ROM games and Card and Board Games including Bridge, BridgeClub, Classic Backgammon, Checkers, Chess, Cribbage, Euchre, Go, Hearts, Reversi, Spades.)
28000-28809 (To play Internet Games that are pre-installed in Windows ME and Windows XP.)
Also, check your firewall to make sure SSL (Secure Socket Layer) is not blocked.
Note for Microsoft Windows 2000 or Windows XP Professional users: In order to play on MSN Games, you will need to log on as an administrator. If you are not logged on as an administrator, you may not be able to install components necessary to run some games or make changes to your computer system’s settings. Please contact the computer’s owner or your network or IT administrator if you need assistance logging on as an administrator.

Games that use DirectX require additional ports to be opened to successfully play through a firewall, proxy server, or router. The ports that need to be opened for DirectX games are:
6073
47624
2300-2400

Revision : 10.0
This article was previously published under Q240429
SUMMARY
This article describes the default ports that are required to play Microsoft Windows DirectX multiplayer games through a firewall, a proxy server, a router, Network Address Translation (NAT), or Internet Connection Sharing. For the specific ports that are required by your game, see the game product documentation. For the ports that are required by games that are published by Microsoft, visit the following Microsoft Web site:

MORE INFORMATION
If you have installed Microsoft Windows XP Service Pack 2 (SP2), see the following articles in the Microsoft Knowledge Base:
842242 (
http://support.microsoft.com/kb/842242/) Some programs seem to stop working after you install Windows XP Service Pack 2

To verify that these ports are open or to open these ports, contact your network administrator or Internet service provider (ISP).
If you are the administrator of the network, see the documentation that is provided with your networking software to determine the steps that you should follow to open these ports.
To play DirectX games through a network firewall or proxy server, the following requirements must be met: • To guarantee DirectPlay compatibility, the latest version of DirectX should be installed on the computers that are used by all players who participate in the game.
• The following TCP and UDP ports must be open on the firewall or proxy server:
Using DirectX 7 or an earlier version
Connection Ports for Client Configuration Ports for Host Configuration
Initial TCP Connection 47624 Outbound 47624 Inbound
Subsequent TCP Inbound 2300-2400 2300-2400
Subsequent TCP Outbound 2300-2400 2300-2400
Subsequent UDP Inbound 2300-2400 2300-2400
Subsequent UDP Outbound 2300-2400 2300-2400
Using DirectX 8 or a later version
Connection Ports for Client Configuration Ports for Host Configuration
Initial UDP Connection 6073 Outbound 6073 Inbound
Subsequent UDP Inbound 2302-2400 2302-2400
Subsequent UDP Outbound 2302-2400 2302-2400
To determine the DirectPlay method for games that use the DirectPlay Lobby service, follow these steps: 1. Click Start, click Run, type dxdiag in the Open box, and then click OK.
2. Click the Save All Information button to save a Dxdiag.txt report.
3. Click Desktop, and then click Save.
4. Open the DxDiag.txt file on your desktop and find the section marked "DirectPlay Lobbyable Apps".
Note that each game listed here will report either "(DX7)" or "(DX8)" which corresponds to its DirectPlay connection method.
Note DirectPlay8 games can work with the Internet Connection Firewall (ICF) capabilities of Microsoft Windows XP. When the game starts to host, enumerate, or connect, the appropriate ports will automatically open and when the game quits, these ports will automatically close.
Additionally, Microsoft Windows Millennium Edition (Me) Internet Connection Sharing, Windows XP Internet Connection Sharing, and UPnP-compliant NATs cooperate with DirectPlay8 to make it possible to run full-featured, DirectPlay8 sessions through the NAT. Users can host or join DirectPlay8 sessions that are hosted inside or outside the NAT. No special configuration is required.
If you are using UPnP compliant network devices and are having difficulty, verify the following: • When you use Windows XP, make sure that you log on as an administrator.
• If you use a hardware NAT, contact the manufacturer to see if the hardware is UPnP-compliant or if there are any updates for it, if it is not.
• When you use Windows XP Internet Connection Sharing, make sure that the Allow other network users to control or disable the shared Internet connection and the Protect my computer and network by limiting or preventing access to this computer from the Internet check boxes are selected in the shared network device's properties.
• A client on a Windows Millennium Edition (Me) Internet Connection Sharing computer must join the session before any client behind the NAT joins the session or else the Internet Connection Sharing computer cannot join.
