Online checker for open ports still reports CLOSED with these rules

Change the "Filter rule association" to "Pass".

As pmhausen mentioned, change Filter rule association to pass.

Also if you are testing the port with regular online port checker, it might not display port as open (unless filter rule association makes that difference) even when it is.

Most online port checking tools won't be able to check if port is open when using UDP protocol (if interested, read about the difference between UDP and TCP. Shortly, both are same, except TCP is slower, more "trustworthy" and visible, UDP is faster, less stable and invisible)
