Issues with moderate Nat On Destiny 2

Hi I'm using a Nighthawk R6700V3 connected to my ISP modem which is a Huawei HG8245H. I have my PC connected directly to the Nighthawk and currently I have moderate NAT. I attempted using port forwarding by forwarding the ports the game use base on the info on their website and it didn't change my NAT to open like it was supposed to. I also tried removing the port forwarding and then enabling UPnP but that didn't change anything either.

I also, tried forwarding the ports from my ISP modem to my Nighthawk and from my Nighthawk to my PC but that didn't work either. So I'm lost, I don't know what to do to get my NAT open.

Any assistance would be greatly appreciated.
