Ports that you must open in Windows Firewall to play or to host an Age of Empires III multiplayer game

Windows Firewall in Microsoft Windows XP

Windows 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.

1. Click Start, click Run, type wscui.cpl, and then click OK.

2. Click Windows Firewall.

3. Click the Exceptions tab, click Add Program, and then click Browse.

4. Locate the executable file for Age of Empires III, and then click Open. By default, the executable file for Age of Empires III is installed in the following location:

   C: \Program Files\Microsoft Games\Age of Empires III\Age3.exe

5. Locate the automatic patcher for Age of Empires III, and then click Open. By default, the automatic patcher for Age of Empires III is installed in the following location:

   C: \Program Files\Microsoft Games\Age of Empires III\Autopatcher.exe

6. Click OK.

7. Click OK to close the Windows Firewall dialog box.

UPnP architecture

With 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:

• Dynamically join a network

• Obtain an IP address

• Convey the capabilities of the device

• Automatically learn about the presence and capabilities of other devices

Devices can subsequently communicate with each other. This makes peer-to-peer networking possible with UPnP.

To enable UPnP in Windows XP, follow these steps:

1. Click Start, and then click Control Panel.

2. Click Add or Remove Programs, and then click Add/Remove Windows Components.

3. In the Components list, click to select the Networking Services check box, and then click Details.

4. In the Networking Services dialog box, click to select the Internet Gateway Device Discovery and Control Client check box.

5. Click to select the UPnP User Interface check box, and then click OK.

6. Click Next, and then click Finish.

To enable UPnP in Windows Vista, follow the instructions provided in the following Windows Help and How-to article.

To make sure that your networking hardware supports UPnP and to obtain instructions about how to enable UPnP, see the documentation that came with your networking hardware.

Port listings for Age of Empires III

If 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:

• Port forwarding must be enabled on the TCP port 80.

• Port forwarding must be enabled on the TCP port 2300.

• Port forwarding must be enabled on the UDP ports that are in the range of 2300 to 2310 from your router to the computer that is hosting the game.

Manual port forwarding

If 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. To do this, click Help and Tools on the main game screen, and then click Update Game. Alternatively, visit the following Microsoft Web site:

http://www.agecommunity.com/gameUpdates.aspx Next, configure the game based on how you want to have the game connect on the network. To do this, set the Override Port and the Override Address in the game settings.
