How to open a port using Windows Firewall in Windows 10 [Tutorial]
In Windows 10, the built-in firewall (also known as Microsoft Defender Firewall or Windows Firewall) is a powerful feature that helps protect your computer and data from outside threats trying to get in and from inside threats trying to get out.
A firewall acts as a gatekeeper and blocks all unnecessary network ports. Every time an app or service tries to communicate outside your device, it checks if there is a specific rule in the database that allows or denies network access. If no rule can be found, it asks you to identify and grant or deny permission.
Sometimes well-known applications (such as SQL Server and QuickBooks) do not work as expected because they are blocked by the Microsoft Defender Firewall. In this case, you must manually create a rule to allow them access to the network.
