Is this a limitation of Debian or the defect in the router or > a configuration hiccup? When you do 'ssh 69.212.23.215 -l username' locally, it is possible that the port forwarding rules of your router are not triggered. Normally, port forwarding of this type forwards from the external interface of the router (the public interface) to the internal interface. In other words, the rule that the router is obeying is "When some connection comes in on port 22 for IP 69.212.23.215 on the external interface, forward it to 192.168.0.101 on the internal interface" A connection from your local machine to 69.212.23.215 does NOT pass over the external interface of your router, and so won't be matched by that rule. It will attempt to login to your router, in fact, via SSH - on its internal (local) interface. Whether you can change the router's behaviour depends on the router itself.
