I assume all your machines in your LAN are using private IP addresses,
and your router is doing NAT for your internal machines to connect to
internet.
For external machine to be able to connect to a service (such as SSH)
running on a internal machine, you need to configure your router to do
"port forwarding", means when when an ssh client connects to port 22
on your router's STATIC IP address, the router needs to forward the
connection to your internal machine running the SSH server.
