So I’ve checked the Geo Filter and it doesn’t look to be popping up with any server information, even though I’ve supposedly set it up for that device (the Xbox). So maybe that is linked to the Prioritization issue too?
The Network Monitor does work and accurately shows the amount of data the Xbox is using, so it’s definitely the correct device.
In terms of Port Forwarding and DMZ, no I haven’t set anything up, nor have I got a Traffic Control rule.
Thanks
