Hi there,
I'm running PS5 connected to XR1000 (wired),
After few months of applying different settings, this what works the best for me:
-Upnp off
-make sure to give static ip for your PS5 in Lan setup
-port forwarding as per picture, this will get you open NAT
-When prioritizing traffic to the same ports as with the forwarding, the rule seems to affect only UDP traffic. So I added prio to whole consle :
add device, basic, game console, normal default. This way I see more packets being prioritized than any other way.
There is no silver bullet for hit detection, it varies from game to game, server to server or peer to peer. However, with above settings I'm having the best results.
