How To Open Port on Windows Firewall

This tutorial intends to teach you to Open a Specific Port (Inbound or Outbound) on Windows Firewall.

To open a port through the firewall on your Windows system, you need to create an inbound and/or outbound rule.

Inbound means someone else from outside of your computer initiates the connection to your computer, so the traffic starts flowing inward to your machine. For example, your server gets requests from people.

Outbound means you initiate the connection and the traffic starts flowing outward of your computer to the destination you intended. For example, you connect to a server.
