Windows Server 2019 includes support for a firewall known as Windows Defender Firewall with Advanced Security. A firewall filters inbound and outbound data traffic on Windows from your Server 2019 instance to protect it from common network attacks.By default, the firewall is configured so that you can access all the preinstalled system programs.
However, different programs may use different plugins to work, and they are usually automatically blocked because they do not comply with the configuration rules of your software. This is in case you ask to open a port specific to Windows Server.
