I got a problem with my extender RE500. Sorry if I selected Adapter as model but I didnt find my model there in the list.

i am playing a game on my nintendo switch and I want to play online.

when I invite a friend I get a NAT error.

I called my provider and they unlocked all blocking ports so now I should be able to play.

if I connect directly to my modem, it works, I can play perfectly.

if I play connected from my extender, it does the same NAT problem.

should I set something on my extender too?

thanks.
