I understand that. But there’s a host of reasons why that night not work - two devices trying to use UPNP behind the 
same PAT device, an apartment complex or hotel WiFi system, etc.

This isn't rocket science.

Give each customer their own ipv4 IP address and turn on upnp, then they will have open NAT to play their game and 
host.

I know the solution is always “IPv6”, but I’m curious if anyone here knows why gaming consoles are so stupid when it 
comes to IPv4?  

We have VoIP and video systems that work fine through multiple layers of PAT and NAT. Why do we still have gaming 
consoles, in 2020, that can’t find their way through a PAT system with STUN or other methods?

It seems like this should be a simple solution, why are we still opening ports or having systems that don’t work?
