Thought this might be helpful as well:
To play DirectX games through a network firewall or proxy server, the following requirements must be met:
• To ensure DirectPlay compatibility, the latest version of DirectX should be installed on the computers 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 method:
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 method:
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 utilize the DirectPlay Lobby service, follow these steps:
1. On the Windows Start menu, click Run.
2. In the Open box, type dxdiag, and then click OK.
3. Click the Save All Information button to save a Dxdiag.txt report.
4. Click Desktop, and then click Save.
5. 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 Windows XP. When the game begins hosting, enumerating, or connecting, the appropriate ports will automatically open and when the game shuts down, these ports will automatically close.
Additionally, Windows Me ICS, Windows XP ICS, 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, please check 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 ICS, 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 Me ICS machine must join the session before any client behind the NAT joins the session or else the ICS machine will not be able to join.
