How To Open Firewall Ports In Windows

A firewall is an essential aspect of computing and no PC should ever be without one. That’s why Windows has one bundled and active as standard. Windows Firewall occasionally has to be told to let a program communicate with the network, which is where opening ports comes in. If you want to open firewall ports in windows here’s how you do it.
Firewalls are designed to protect a network from threats. Either threats from the outside trying to get in or threats from the inside trying to get out. It does this by blocking network-enabled ports. Every time a program tries to communicate through this port, the firewall checks its database of rules to see if it is allowed or not. If it doesn’t know, it asks you, which is why you sometimes see prompts asking you if a particular program is permitted to access the internet.

  8. Name the rule something meaningful and click Finish.
