How can I disable any TCP/IP port on a Windows 7 machine?

I need help on finding out how to disable any particular TCP/IP port on a Windows box whenever a need arises.

I googled before posting the question and I got links to articles mentioning only

  • disabling services for a particular port
  • disabling net bios ports
  • port forwarding on a router
  • etc

But none of these topic cover what I'm looking for.

does this work for localhost too? Because I can't block requests to my localhost with this rule unfortunately. – Capaj – 2014-08-15T16:21:48.260
