Guys, I need your help ! While I have no problem with NAT on my PS4, Xbox One or WiiU I have NAT problem with my Switch. I am getting type C-D (mostly D) and I do not know what the hell is going on. I mean, on my PS4, I am always getting Type 2 and my Modem/Router support UPnP. Never had any problems with P2P gaming on my WiiU. Any ideas ? My router is TP-Link Archer MR200.
