Our Rating: (Good)

Port Detective is a simple tool, that helps you find out what ports are blocked by your router/firewall or ISP. It comes pre-configured for the most commonly used ports, and you can also add your own ports to the list. The program is intended to check the availability of common ports for the purpose of self-hosting, as many ISPs are blocking these ports to prevent users from running public web servers, mail servers etc. on their home computers.
