Windows 10: Blocked Ports in Firewall but TCPView says they're still in use.

  1.    29 Nov 2017 #1

    Blocked Ports in Firewall but TCPView says they're still in use.

    Blocked a range of ports via my Firewall but TCPView says they're still being used to connect to the network.

    What is causing this and is there a way to configure the Firewall to automatically block specific ports regardless of protocol, stateless/stateful nature and other invasive networking technologies that override Firewall settings that have a clear purpose?

    Much appreciated.

    A screen would help, you might be seeing loopback connections.

    Blocking ports means nothing from the outside can enter via those ports but if an internal programme opens the ports then they are open to that software

    So a program that is set by the access list of the Firewall to 'allowed' overrides specifically blocked ports?

    If you only block ports in then software can open them out you need to block in and out
