Open or close a port in Windows Firewall
Security must be considered an essential aspect of any computer network. No PC should ever be run unless there’s a good Firewall in place.
Luckily for us, Windows offers its own firewall, but it occasionally has to be configured to enable a program to communicate with the network. This is where the task of opening ports comes in.
In this tutorial, we will show you how to open or close a port in Windows Firewall by creating a new rule.
- Open Windows Firewall.
- Right-click on Inbound Rules if you want to create an inbound rule, or Outbound Rules if you want to create an outbound rule, and then go to New rule.
- Now select whether it is going to be an application or a port.
- Select the protocol and add the port. If there are several ports to open in the same rule, you can separate them with a comma, or even open them by ranges using a dash.
- Select “Allow the connection” or “Block the connection” depending on whether you want to open or close the ports.
- Select all profiles.
- Finally, give the rule a name and then save your changes.
Now you are ready to go!
