I have Nat Reflection enabled and Filter Rule Association "Pass", but otherwise, it should work.

Remember to configure remote access in your plex instance on port 32400.

Is there an updated version of this? I have not been able to get remote access working since moving to OPNSense. I did notice that if I disable and re-enable remote access, It will be fully accessible for 4 seconds then it goes back to "Not available outside your network".

I think, it will only work if you are able to access the remote port via IPv4, e.g. you are not behind CG-NAT or any type of double NAT, for that matter.

Also, my firewall optimization is set to "normal", see attached pictures. Obviously, you will need a plex account and have outbound access for your Plex server as well such that the plex network can make your external IPv4 be found. This server may not use a VPN connection, and obviously, you need a static or reserved internal IPv4.

There are instructions on how to test this (see sections "manual port forwarding" and "common problems"). For example, Zenarmor or AdGuardHome could also interfere.
