I'm not able to get get NAT Type Open on my Xbox One X, it's on Strict, as I type this post, and shows UPnP Disabled, while PlayStation 4 Pro shows Open NAT inside Call of Duty : Modern Warfare after Port Forwarding. I have port forwarded to Xbox One ports as well, but can't get it to work. UPnP generally fixes this, but I can't get UPnP to work. It shows "There are no Redirects" even when my PlayStation or Xbox One is connected and playing a multiplayer match.
My internet setup
ONT/ONU (Bridge Mode) -> Raspberry Pi 4B (Router, PPPoE configration) -> Tp-Link Archer AX50 (Access Point Mode, DHCP off) -> PlayStation 4 Pro and Xbox One X through LAN Cable from AP.
Any help is appreciated.
