This article describes the ports that you must open in Microsoft Windows Firewall to play or to host a Microsoft Age of Empires III multiplayer game. Additionally, this article describes the advantages of enabling UPnP architecture that supports peer-to-peer Plug and Play functionality for network devices.
This article also lists the port addresses that must be open on computers that are not running Windows Firewall but instead are using a proxy server, a router, Network Address Translation (NAT), or Internet Connection Sharing.
Windows Firewall in Microsoft Windows XPWindows Firewall, previously known as Internet Connection Firewall (ICF), is a protective boundary that monitors and restricts information that travels between your computer and a network or between your computer and the Internet. This provides a line of defense against someone who might try to access your computer from outside Windows Firewall without your permission.
When you use Windows XP Service Pack 2 (SP2), you do not have to manually create port exceptions in Windows Firewall. Instead, you can create exceptions for the program itself. In this case, when the program tries to access a port, Windows Firewall enables access to that port.
To create exceptions for a program in Windows XP, follow these steps.
Note Do not open a port for a program that you do not recognize.

UPnP architectureWith the addition of Device Plug and Play capabilities to the operating system, it became much easier to set up, configure, and add peripherals to a computer. UPnP extends this simplicity to include the whole network by enabling discovery and control of networked devices and services, such as network-attached printers, Internet gateways, and consumer electronics equipment. UPnP is more than just a simple extension of the Plug and Play peripheral model. UPnP is designed to support zero-configuration networks and automatic discovery for a variety of device categories from many vendors. With UPnP, a device can do the following things:

Port listings for Age of Empires IIIIf you do not use the Windows Firewall program, you can still open the ports that are used by the game when you configure the network.
To make sure that these ports are open, or to open these ports, contact the network administrator or the Internet service provider (ISP). If you are the administrator of the network, see the documentation that is provided with your networking software to determine how to open these ports.
The following list explains the port configuration specifications for the game:
Manual port forwardingIf you use port forwarding on the network and want to manually configure the game, you must first download and then install the latest version of Age of Empires III.

Override PortThe Override Port will let you specify a port to use instead of relying on UPnP or the game's port discovery process. This port is useful when you have multiple PCs behind the same NAT and you want to use port forwarding. To use Override Port, follow these steps:
Override AddressThe Override Address will let you specify an external IP address to use instead of relying on the address that comes back from the game's address server or with LAN, the internal IP that the game uses. To use the Override Address, follow these steps:
