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:

127.0.0.1:5000 > 10.0.1.50:22
127.0.0.1:5001 > 10.0.1.51:22
127.0.0.1:5028 > 10.0.7.32:22
127.0.0.1:5176 > 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.
