Hello, I tell you what is happening to me ...
I have configured the geofilter in a radius of 3000km with center in Madrid, to play Splatoon 2 I have to allow a Peer server in the US, I give it to allow but it happens to me that sometimes when it tries to reconnect with server it blocks it and I have to give it again to allow, being the same server because it appears with the same name that had allowed it before.
It also happens to me that I am noticing an excess of lag, I play through cable, I am noticing it in games like Splatoon 2, Paladins and Rocket League ... with the antibufferbloat in 70% when it detects priority traffic. I have added the Nintendo Switch as a device manually, including all ports, from first to last and in both protocols. But the speed tests work well for me.
I was also disconnected the cable network connection when I was playing, having to reconnect ... this has only happened to me once.
As a suggestion as a nintendo switch user, I would like you to add this console as a device, and I also hope to use any VPN client, in my case ipvanish.
