I think this question is related to your PR kern/84215.

The current situation is: jails take precendence. So if sshd is
listening on inaddr_any on the host and on inaddr_any inside a jail
the connection to an IP belonging to a jail will end up inside the
jail; any connections to IPs not beloning to jails will end up on the
base.
Obviously if you stop the jail and ssh to a former jail IP you'll end
up on the bsae system and ssh would complain about different keys
possibly while telnet or similar things won't notice.
