Keep in mind: a Reverse Proxy makes all requests to the Plex server appear like they are coming from within the local LAN.
If you now combine this reverse proxy with a rule to disable the need to authenticate when a client accesses your Plex server from within the local network, you are wide open to unauthorized access.
(Settings - Server - ‘Show Advanced’ - “List of IP addresses and networks that are allowed without auth”)
So, don’t use these both together.
