gateway : The computer to whom a node connect to have access to the 
subnet (usually the ConnectTo line in tinc.conf
IP address : the private and non-routable-over-the-internet IP address 
the node uses for itself in the VPN.

In my VPN, most (if not all) of the keys have this kind of header

#Name = Foobarlol
Address = public_ip
Subnet = tinc_ip/32
Port = 1042

And err404 was the one who led the tests ;)
