Most online port checks assume that you already have an application (such as your game or torrent) listening for the port test on your computer, and then assume that the test was OK simply because they were able to connect to your computer.
Also, web only port checkers are not able to test UDP since UDP is a connectionless protocol and there is no way to know if the packet actually made it to your computer without some sort of program on your computer waiting for that packet.
With our open port check tool you never get a false positive!
PFPort Check is a smart and friendly tool that allows you to checks the open ports.
