You don't really need to change the ports on the hosts. Just configure the
router to accept different ports on the internet side and redirect to port 22 at
the different IP addresses on the inside. Then you only have to change the
client settings for access from outside. I'd move both of them away from port
22 on the outside, though - you'll avoid a lot of password guessing attempts
that will happen otherwise.
