a little clarification, ssh into your router (ssh root@router-public-ip) and then in your ssh session since your connected into your router controlling it, ssh to your other machines (ssh root@local-machine-ip)
this does work, i set up openwrt and did this alot. its just opening up port 22 in your firewall so your router accepts connections from the world.
