@RedBull2k In order to get it working, I assume I need to proxy my PS4 through my pc running the app in order for it to pick up on the ports being used? 
@MassaDebata85 You're right, there is very little info about what this program does on this thread. I believe, after reading through the forum, it picks up on the exact ports used by Call of Duty and prioritizes them on the router QoS (and a couple other features like saving and loading Allow/Deny lists). Somebody on the forums figured out that CoD uses a random port for each server connection (port 3074 on your PS4 and a random port from 30000-45000 from the server). This program should eliminate the need to use wireshark to figure out the ports and manually add the ports every game.

Works flawlessly! I even disabled DumaOs Games and it's still detected as High Priority!
Nice work mate, you need to set up a donation page or something if you plan on continuing support for this. And Duma devs should pay you to implement this feature into their OS...
