Plex Indirect Access on LAN with OPNSense / Unbound DNS

Some devices on my network were unable to access Plex directly since migrating to OPNSense with Unbound DNS.

After much troubleshooting adding plex.direct to Services->Unbound DNS->Advanced->Private Domains and applying/restarting Unbound those devices now connect directly.

opnsense config screenshot showing "plex.direct" as the only entry to the "Private Domains" category — plex.direct private domain entry

Happy (local) streaming!
