This is likely quite true Michael, but it also is only a hint as to how
to fix it for the OP. I maintain 8 to 12 such ssh connections here to
my othermachines, establishing them at boot time, but all are local
192.168.xx.xx addresses so not NAT'd going either direction, so I am not
affected. I would be upset if I was.
