Firewalls are meant to protect your computer from any external network related threat, unauthorized access to control the computer or access the data stored on the computer. By default, certain services have certain ports, for examples, web browsers use a port number, Email client use a different port number and certain other multimedia protocols have their own port numbers. Out of these ports, some are open or unblocked by default while the other are closed in the Windows 8 firewall. In this article, we tell you how you can specifically block or unblock a certain port number in Windows 8.
