Microsoft Windows firewallWindows Firewall, previously known as Internet Connection Firewall (ICF), is a protective boundary that monitors and restricts information that travels between a computer and a network or the Internet. This boundary provides a line of defense against someone who might try to access your computer from outside the Windows Firewall without your permission. By default, Windows Firewall is turned on when you are running Microsoft Windows XP Service Pack 2 (SP2). When you use Windows XP SP2, you do not have to manually create port exceptions in the firewall. You can create exceptions for the program itself. To do this, follow these steps.
Note Do not open a port for a program that you do not recognize.

UPnPWith the addition of Device Plug and Play capabilities to Windows XP SP2, it is easier to set up, to configure, and to 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 merely 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. Together with UPnP, a device can perform the following tasks:
To enable UPnP, follow these steps:

Port listingIf you do not use the Windows Firewall program, you can still open the ports that are used by Flight Simulator X when you configure the network. To make sure that these ports are open or to open these ports, contact the network administrator or your Internet service provider (ISP). If you are the administrator of the network, view the documentation that is provided with your networking software to determine how to open these ports.
