XR500/COD/Hybrid VPN/Open Nat in game sometimes works and sometimes doesn't

[brokenbones]

Has anyone figured out the problem yet?

Sometimes I have open NAT in the game and other times it is moderate. Is this a VPN issue or a port forwarding issue?

My setup: (that works periodically)
I am running fiber direct from wall into XR500. (No residential gateway)
DMZ set to console. Static IP assigned to console outside of LAN range.
Nat Filtering: Open
Port Forwarding Static IP:  TCP/UDP 20-21, 80, 443, 1935, 3074, 3478-3480
UPNP Enabled
Geofilter: Off
QOS: ON 
DumaOS Classified Games: ON
Hybrid VPN: On, Block Traffic if VPN disconnects=Off, VPN Traffic = Console device added

It's because you're using a VPN, if you're using it then it's unlikely you will receive an Open NAT.
