Not using sshd on the machine with port 2205 open, .. sshd is on the other
end of the tunnel (port 2206, which does work properly). Unless I am
missing the point?

It *does* only show localhost:

tcp        0      0 127.0.0.1:2205          0.0.0.0:*               LISTEN
tcp        0      0 ::1:2205                :::*                    LISTEN

Why would it not bind to the IP used in the connect?
