Behind vpn and dns. No connection

[TheDreadPirate]

Do you have a bunch of users that aren't in your family? If not, I'm not sure what the benefit is of having a 3rd party VPN service. You only need to be concerned about hiding your WAN IP if you have people you don't trust connecting to your Jellyfin.

But if you just need a VPN to avoid directly exposing Jellyfin, you can use the built in Open VPN server your router already has. In the UI you would provide your DDNS hostname (since that is embedded in the config) and then you can export the client config to use with your devices that will be accessing Jellyfin remotely.
