SSH access to machine behind router

[Daniel Gimpelevich]

What you can do is forward multiple ports on the router to port 22 on
different machines. Then you can use the -p option to ssh to select which
machine to connect to. This is how my setup was when I was using a router
that supported it, which I'm sure most routers do. The disadvantage to
this method is that you have to delete the known_hosts file prior to every
connect attempt.
