https://support.plex.tv/articles/200890058-authentication-for-local-network-access/ https://support.plex.tv/articles/200890058-authentication-fo... In rare cases, you may decide that you wish to allow very specific access from the local network without authentication. You might do this if using a third-party Plex app, which doesn’t support authentication, for instance (though all modern official and third-party apps should already support authentication). To make an exception, look in your Plex Media Server’s advanced network settings, under Settings > Server > Network > List of IP addresses and networks that are allowed without auth. Here, you can specify LAN addresses as either a specific IP or a IP/netmask (to specify a range). Separate multiple values by a comma and be sure not to include any whitespace (e.g. spaces).
