Not every game are made the same or use the same network engine. Which games on PS4 are more problematic in your opinion?

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. On Sep 27, 2020, at 2:17 PM, Darin Steffl <darin.steffl@mnwifi.com <mailto:darin.steffl@mnwifi.com> > wrote: 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.

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?
