It’s been a while since I’ve played any games online with my Nintendo switch, and I quickly remembered the issues with NAT types on the Switch.

When I checked, I had a NAT type of F, which will not allow online gaming. I found the guides on setting up the Hybrid NAT rules in Pfsense, but my type was still F. I then loosened up my outgoing port rules for that VLAN, and got a NAT type of B.

After tightening them back up a bit and looking online, it looks like the UDP range 1024 through 65535 is expected for outgoing UDP traffic. Is that right? That is a ton of ports, and possibly no better than just enabling uPnP.

Do I really need such a wide range to be able to maintain this NAT type B?

    Can confirm that also works on OPN

    Static outbound is a feature I wish more firewalls had because it requires the targeted device to send outbound once before it accepts incoming (or at least that’s my understanding)
