Due to firewall reasons, I have changed the standard RDP port by the port 22 by following this:
After reboot, I try to connect with remote desktop using IP:22 but I have no answer. Of course, I have no answer anymore from port 3389.
Is it possible to do a RDP connection via port 22? If so, how can I debug deeply?
I have opened my firewall to allow incoming connections through port 22.

What happens when you just ssh using PuTTY or similar to your network? Do you get a login prompt from your router? Some routers have a built-in
sshdthat may need to be turned off first. – LawrenceC – 2019-11-27T16:16:50.043It would be easier to change your firewall to allow 3389, but look at this Microsoft article to see if it helps you change the port number: https://docs.microsoft.com/en-us/windows-server/remote/remote-desktop-services/clients/change-listening-port

@John Yes, this is exactly the article I followed to change the port. Unfortunately I have no rights to manage the firewall – Zumo de Vidrio – 2019-11-27T17:09:02.860
@ZumodeVidrio basically the router may be listening on port 22 and not letting anything through. – LawrenceC – 2019-11-27T17:18:16.203
@LawrenceC Dont think so because if I change the windows VM for a Linux one, the SSH connection is properly established – Zumo de Vidrio – 2019-11-27T17:44:31.350
