I found the ports for warzone but I'm little confused at how to insert them, should I let source port default (1-65335) or should I change to 3074 (for example, one of the ports) and the destination port 3074.
And also, which is better, to use the Games Console ports or to set manually, and if I use both it will be any problems?
You keep the source port default and change the destination port. Classified Games/Games Console will prioritize it anyway but some people like to choose ports instead. I would recommend you have one or the other enabled, not both.
Normal is if you're playing over ethernet, Gaming/voice is if you're using WiFi. Apply to WAN is optional, if your ISP supports priority tags then you may have slightly increased performance with it enabled.
