How to Configure Ports on Windows XP Firewall

With Windows XP, Microsoft introduced a firewall included with its operating system. Providing a firewall with XP was an attempt to assist users in securing their computer from Internet security threats. Not using a firewall allows all ports to be open to intruders. The firewall allows both TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) to be opened for specific ports. Applications that communicate to users or to a central computer over the Internet require one or more ports to be opened in the firewall.
