OK… So I’m running an internal (home network based) Plex server for a few years now… Works great. I want to make it available to my daughter going off to college.
I setup the port forwarding on my router and I can access the Plex dashboard via web browser but how do I configure APPS like on her Roku, or the Plex App on her iPhone to use this new external address for my media server instead of the internal one it currently uses??
The internal name, and the external DNS are completely different…
You shouldn’t have to.
If the Roku is linked to your account and you have remote access enabled on your server, the Roku should be able to access your server’s media.
The same applies if you have remote access enabled and she’s using her own account, assuming you shared your library with her.
No additional configuration should be needed on the Roku.
Plex doesn’t use a domain name for remote access… most users don’t have their own local / global domain names.
Instead it’s directly using the public IP address determined for the server.
The way I understand it, your server reports it’s last known public IP address (that, given to you by your ISP) to Plex. When your device connects to your account, it checks what servers are associated to your account and where to find them with Plex and then directly connects to that server.
That’s why you don’t need to configure each individual Plex client with the network details of your Plex Media Server or update it whenever your ISP reassigns a new public IP to your home network.
