RE: IPv4 flag day

Works fine with NAT *with the caveat that there are a lot of workarounds and netcode issues*

Without NAT it's a hell of a lot more reliable.

There's a reason I ripped out all my NAT supporting code and don't support NAT scenarios outside of 1:1 NAT.

More and more use web-based services that use WebRTC. Works fine with NAT and SPI firewalls.

Teams uses that.
