Question to the OP please. Are you also behind your own router?
Does it run NAT? If yes, is it configured to forward an ssh connection,
from the Internet, to your local host?
No, I am not. I do not have any router. My laptop is connecting via
mobile broadband and have a global IP.
$ ifconfig

If I switch my connection to another provider, so that I have my own
router, and the IP of the nodes are no longer global, (IP range
192.168.1. 1 etc), I can ssh between them, as well as to outside.
