holy crap the screenshots are useless, the forum reduced them to junk ...
no Armour, no DMZ, only had QoS an Geo-Fence set for the 3 NAE Fortnite servers. No other rules, etc, other than what the router does by default via the Nighthawk app and or stock behavior of the firmware.
I have done a factory reset, and about 8 different ways to try to isolate it. as both CONSOLE and COMPUTER under Geo-Fence.
I tried it Geo-Fence with my computers as a device: COMPUTER and all the steps listed in first post.
Then tried Geo-Fence with the computers set as device: CONSOLE/ PLAYSTATION and all the testing steps.
I then did a factory reset, setup the router as New Out of Box with the Nighthawk App(Annoying AF), and tested again with my PCs set as device: CONSOLE in Geo-Fence and still the same results.
So now it is back to devices as COMPUTERS, and QoS is set to: By DEVICE, not By APPLICATION. and my two computers have all of the Bandwidth. while it sort of works, it is not making the gaming data priority, it is still FIFO of the queue as delivered to my IP Address and then handled by the router.
Something changed, either on Epic Games side with fortnite, the NetDuma side or both around the patch right before Fortnite went to Season 4.
All that I do know, at this point, is my XR1000 is not doing much for my Fortnite latency or keeping me locked to the servers I want now.
Straight up, I have worked on this almost every night since I noticed it right around September 11th or so.
