try  these ports and run these in your powershell as admin opend my nat when nothing eles would hope this helps
ports to foward on r3 router
    TCP: 3074,3075,27015-27030,27036-27037

On Call of Duty PC to get open NAT via UPNP I switched my connection to private and not public to allow sharing. Then by clicking on the properties of the Duma R3 I shared the ports I needed, in this way I was able to view UPNP working in R3

That is great. Thank you for showing the photos. As long as no traffic was on the network at the time it shows that there is an issue. Would be nice to have closed PingPlotter as the R2 test lost its target source.
It’s almost as if traffic is being sent out without any internal control. Would be interesting to know if any traffic is seen using something like wireshark. 

I have ran multiple pingplotter tests at this point on the r2 and r3 with nothing connected at all besides the pc running pingplotter, I even ran it pinging my ip, on the ip itself test for the r2 stays about 0.4-0.5ms with the highest being 0.8ms in a 10 minute test. The R3 varies constantly up to 4 ms. So something is causing it to keep spiking, definitely don’t think it’s my network either as there is another guy on here that has reported the same and my buddies does the same thing. For reference on the r2 that graph never goes over the 1ms line compared to it going over the 4ms line here

This is in line with what I experienced using the simple Bufferbloat tests. Higher jitter and higher lag spikes when connection was on idle.

So here's an example. CC Enabled (Speedtest Bypass Off) with 100/100 for both the R2 and R3 + R3 w Steady Ping

R2
25th %ile: 3.2 ms
75th %ile: 3.9 ms
95th %ile: 4.3 ms
Jitter: 0.5 ms

R3
25th %ile: 7.3 ms
75th %ile: 9.5 ms
95th %ile: 12.6 ms
Jitter: 1.6 ms

R3 with Steady Ping
25th %ile: 3.5 ms
75th %ile: 4.5 ms
95th %ile: 7.2 ms
Jitter: 0.8 ms

There two factors the way the engine is designed were a player can slide and they see you first do a little bit of research on that it laughable that a thing and then of course ping to the server whoever has better ping has an advantage and if your skilled at the game and unlucky on the location you live upon they'll put you to play against people that have similar skill but that affects your ping since all of them somehow live in the middle of nowhere and that were the dedicated servers for competitive are....
Why do you think every esport players live next to the dedicated competitive servers? Simple it because they know it has an advantage ping is king and I don't blame them for that but when you can be playing at 20 ping and you want to be competitive and the server is 100+ms you can't necessarily have a fair fight and say your better at the end of the day were still waiting for fiber speeds promised decades ago. They should be making improvements to infrastructure though I can't even trust companies that false advertise 5G and then expect the future to be any better.
What really worries me is the new sbmm systems they're implementing were the game is rigged and it not even fair at that point decreasing damage etc I can 100% attest this is definitely being implemented or probably already is it just it hard to notice I know if a cheater on warzone uses cheats they definitely get those sbmm system rules that have been heard of so if they're being used on them who knows what they're being used for as well.

I’d like to be added aswell

I'm like .9 k/d and it takes 5-10 minutes to find a match.  Then my run ins with cheaters seemed to be two or three times more likely.
I tried forcing near by servers and no geo filter.  Didn't seem to matter to me.
Changing your GEO is supposed to break the SBMM, but there has to be more to it.  Or I am still doing something wrong.  I feel like I have much more EOMM than who I'm matched up with.  I didn't play for a couple days then the first game back I was beaming people.  Then within 2 more games it was back to running in mud, emptying mags into people, and barely getting shot to go down.

For me, it's wind....a waste of money.
WG works fine without...
