You're top posting. Some folks around here frown on that.

Your router can hit your box because it knows where it is. A machine 
somewhere out on the internet can hit your router because it has a 
public IP and therefore knows where it is. Your machine only has a 
private IP, so its invisible in the direction from Internet to your 
machine. You can see out from your machine because your router is 
probably NATing the traffic to its IP address.

To be able to hit your internal machine from the outside world, you have 
to give your internal machine a public IP address, or tell your router 
to port forward SSH traffic to the internal address.
