Plex through Wireguard

Have installed Plex on TrueNAS Scale and it works when I’m on Wifi.
But I can’t get through to Plex when I’m outside home through Wireguard. Wireguard is working and settings is on 0.0.0.0 (all Networks)

Wireguard IP: *.0.5.1
Plex IP: *.0.10.40
pfSense IP: *.0.10.1

Wireguard is set up after Tom’s video.

What firewall rule do I need to get this to work.

Can you ping the TrueNAS when on Wireguard?

Fix it now.

Just reinstalled Plex and gave the dataset the right permissions.

Thx for the help…
