Server isn't reachable outside the local network

[jacopograndi]

Known issue

I tried passing my public_ip:port as the server public address and binding the socket to localhost:port. Forwarded the port from the nat, but no connection was made. The port was closed even to port checkers, not that it's strong evidence of it being closed.

Probably I have missed something, probably is my nat doing what it does best. (testing my patience).

I had to bind both client and server sockets to 0.0.0.0 to get it working
