UPnP and NAT-PnP - Net code is a bit shakey

[ZkepZ]

Please review your netcode, I got basic security running on my network, at a point where I am not willing to open more stuff. Works for all other games I play without a hitch and I commonly host games like space engineers and other survival games.

On top of your UPnP code I am hoping you will make it compatible with NAT-PnP too, then you probably capture 99% of the router implementations used today if not 100%.

I have yet been able to actually establish a coop session with anyone using an airport extreme, probably because of it using NAT-PnP instead of UPnP.
