What is Firewall?

A Firewall keeps a computer network safe and secure. Windows Firewall is such a kind of packet filtering software component by Microsoft Corp. Although firewall can be both, hardware based or software based but its main functionality is controlling and checking incoming and outgoing traffic by examining the data packets. The firewall then determines which packet id safe, which to forward, which one is harmful and thereby to be dropped. This forwarding or blocking of packets is based on certain protocols or a set of predefined rules and regulations. Firewall logically builds a wall or partition between an internal network and an external network. The internal network is presumed to be safe and secured but not the external one. Operating systems generally use software-based firewalls and the Windows Firewall is one of them. In the following tutorial I’ll tell you how to configure this firewall to block specific applications or all.

  1. The Firewall service has to be runinng whether the firewall is enabled or not. VMware does not check to see if the firewall is up before it tries to modify the open ports list. Once VC, UM, Composer, etc are installed, then the firewall service can be disabled in Services.
