What are the greyed out ports in my Windows Firewall?


These ports are open on the internal network port only. They are blocked on the public network connection. The internal network is a secured thus having these ports open is considered secured also.

These ports cannot be modified unless you reset your firewall rules. This will clear them from the Exceptions list of your Firewall. Please note that resetting the firewall rules may affect not only additional services in use but also could cause other issues as well with your server depending on how you configured your server.
