The working of Windows® Firewall


Windows® Firewall observes all network traffic on the connections for which it is enabled. It also keeps track of all communications from your computer and prevents unsolicited traffic before it reaches your PC. If needed, the firewall opens certain ports with dynamism and permits your computer to receive traffic that is requested specifically. A port is a networking term that recognizes the spot at which a type of network traffic arrives at your computer. The accurate port that you open depends on the type of traffic you are interested to receive or send. In case you need to block incoming traffic, Windows® Firewall blocks it before it reaches your computer. For some special uses like hosting your own web server, hosting online games and networking, you can choose ports that you want to leave open. Windows® Firewall forms part of Windows® XP SP2 or higher Professional Edition, Windows® XP SP2 or higher Home Edition and Windows Vista®.

Why the firewall blocks some programs to run on a computer?


To provide security for your Windows® XP SP2 based computer, Windows® Firewall blocks some programs that are server-based or client-based, which communicate over a network or over the Internet. Some of these programs are Windows® XP SP2 based server program that responds to the requests of the clients, Windows® XP SP2 based client based programs that receive data from a server and instant message and multiplayer programs that are using the Internet. So, the reason for blockage of some programs by Windows® Firewall is the security of your computer.

How to enable programs using Windows® Firewall?


Some games and programs should receive information over the network for proper working. This information enters your computer through an inbound port. The appropriate inbound port must be kept open on your computer so that Windows® Firewall can permit the required information to enter your PC.
