Alright, I'm slowly learning, bare with me here:
- ProtonVPN is always-on and blocks connections without VPN
- Jellyfin and Headscale are hosted on the Pi (or does Headscale need its own server?)
- Tailscale and a Jellyfin client are installed on the phone
Then:
- Will that will run fully on the LAN?
- Will it be encrypted during transit?
- Does ProtonVPN need to allow LAN connections?
By "local-only" I meant on-device
Privacy and security.
Networks are not a trusted party in any capacity.
A VPN such as ProtonVPN or Mullvad VPN are used to displace trust from your ISP into your VPN provider and obscure your IP address while web browsing (among other benefits that I don't utilize).
These are good questions but not ones I can answer briefly.
