Help with Opensense and Nintendo NAT D

[Manaboy]

Hi guys, anyone know how to solve the NAT D issue and error 2618-0521 on smash?

I'm able to redownload my games from eshop, play cloud games such as kingdom hearts 3 however only able to play tournament mode on smash. Apparently it's because my NAT is D when it should be A or B.

My setup is Andrew and Arnold FTTP ONT connected directly to my Opensense system.





Any help is appreciated
