Re: Hub 3.0 Port Forwarding issue - Not saving changes
To be frank while it may work, it's a ridiculous solution.
There's no way you should need to forward that many ports and as for the Nintendo advice of forward ports 1-65535 UDP is almost the same as putting the Nintendo Switch in the DMZ - except only forwarding UDP and not TCP connections.
Games aren't usually listening on such a wide range of ports, and it's only the ports listening for new inbound connections that need forwarding. If you've got UPnP enabled I'd normally expect the game itself to be able to open the ports it needs.
