No, I am not. I do not have any router. My laptop is connecting via
mobile broadband and have a global IP.

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.
