    All was well when I used 3389. I am a bit anal and thought I would change the port for security reasons. I selected 59630. (Guess it's not secure now!!) I selected 59630 because it was not assigned according to IANA.ORG.

    I (correctly) port-forwarded my router. I tried 59630-59630 and then 59630-59631. My machine is the target; my associate's machine initiates. Regedit mods completed. Both 59630 and 59631 have been attempted. I have run PFPortChecker and it says they are open (59630 only on UDP - 59631 open on both). I just ran it again to verify. Albeit, when connection is attempted, it fails; saying port not open...

    Question 1: Are there some ports not allowed/authorized for Remote Desktop?
    Question 2: What is my next step?

    Thanks, in advance, for your help!!

    It probably works like FTP and the port you open is initially is only a control port. The data port is chosen later, sometimes randomly. In any case, all ports used would have to be coordinated between the connected machines. It could also be that the target machines will only accept connection from a particular origin port.

    It is already secure. Stick with the defaults.
