So I try to do get into some netplay action...and soon learn that due to "Restrictive NAT", I can't attempt to start a game.
The restrictive NAT warning means you can't join another player with a restrictive NAT label. However you can still join other players (even some NAT players), and they can join you. It's just a certain combination of NATs that don't play well with each other.
As for starting a game, you just click the name of another player to invite them. There is no separate step to "host" a game.

There is absolutely no documentation, so I can't find what ports are required to set.
It's UDP port 33333, but try a few games without mucking with your NAT -- I think you'll find the game copes pretty well.
