[ENet-discuss] NAT punch through

[Lee Salzman]

Yeah, just play with the socket functions. they're not terribly 
documented at this point because they're only used as an interface for 
ENet to implement itself. At some point I will make them a more 
"official" part of the interface.

The best reference for using them is to just look at unix.c, and then 
look at the corresponding man pages for the involved unix sockets 
functions when it's not entirely obvious what they do.
