Oh, I forgot about the system log in the router, no it doesn't show me the ports listed when launching a game, unless I set a DMZ or Open NAT, then it does.
I tested listening porta to on my pc by launching a game that utilizes UPNP and then I check if ports are open using port checker tools.

Another way to check...
ASUS ROG RAPTURE GT-AXE16000 Firmware version 3006.102.6 UPNP not working unless DMZ/OPEN NAT is enabled for a specific IP address and port.
I'm aware that Asus routers with the new Broadcom chips are limited to a port restricted cone NAT, but I'm pretty sure that UPNP should still work alone...
