UDP Hole Punching / NAT Transversal — at Version 7

Description (last modified by )
Details
Right now in 0 A.D. we use a primitive UPnP system to implement NAT transversal but this system is unreliable. We'd like to see a better method using UDP Hole Punching instead. The solution would most likely involve interacting with the lobby server to get transversal information but it could also involve using something like STUN.
Expected Result
Enabling 0 A.D. clients to connect to a host behind any type of NAT.
Required Prerequisites
Fluency in C++ and understanding of NAT transversal. JavaScript knowledge would also be recommended. (Ability to learn/familiarity with erlang would also be required when dealing with the lobby server)

Because we now have UPnP-based automatic port forwarding (which serves nearly the same purpose), I'm dropping this ticket's priority.

I'm not really working on this anymore as I have not been able to fully understand what implementing this would require.
