 But because you do not store the port number it will cause issues. Perhaps
 I did not explain this properly.

 For example, if you setup SSH port forwarding tunnels: > > > > 80.xxx.xxx.xxx:22

 These are port forwarding to unique servers with unique fingerprints.

 In mountain duck if I connect to server1 and save the fingerprint, then
 connect to server2, it will say the fingerprint has changed. If I save
 server2 fingerprint and then connect to server1, it will say the key has
 changed because it only stores the fingerprint for the IP, not IP:PORT.

 OpenSSH has supported this for over 10 years.

 This does  not affect macOS.
