HOWTO: XBOX One and Open NAT

[WaxBear_79]

I've had to allow uPnP (ports 5351, 1900 and 2189 to the firewall) and IGMP (to 224.0.0.2) to make this work, since my Xbox resides on my IoT VLAN which has limited access.

Following the manual on https://www.amixa.com/blog/2020/04/02/how-to-get-open-nat-with-xbox-or-xbox-one-and-pfsense-firewall/ and adding these rules now NAT is detected as open by the Xbox.
