Well I haven't used wireshark, But I tested making a rule for UDP 3074, one for local, and one for remote. Remote really didn't do much in terms of traffic being passed, while in a match. However when I used UDP with local port of 3074. Whenever, in a lobby, and a match being played. Data was being passed on the priority I set it to. Once matches are over, data rates drop, and when I back out of a lobby. Data being passed over the rule I created, is nothing.
So that tells me for at least COD for me, on PS4, UDP with local port set to 3074. Is the perfect rule to give in game traffic, the best possible priority. As server IP's, and such change to much, to try to narrow down a IP range to only give priority for game traffic.
EDIT: I also rerouted the couple things within my home network, that passes traffic over FreshJR's top priority Net Control Packets, to another priority. I ended up putting the COD rule I made into Net Control Packets, so that priority is totally empty, and only traffic from the rule I created, will be passed over it. For me, it made it much easier to know if the rule was working properly while in game, without any other traffic being merged with it.
