This is exactly the same setup I have at home, Clint. But as Matt states,
you need to configure your router to forward port 22 to at least one machine
on the inside.

In my setup, my fw/router accepts SSH but forwards it to my Linux box. I can
then get to any of the other machines on the inside from there. I typically
port forward VNC or something so I can run my desktop at home from my
machine at work.
