What added security do you get by using a VPS besides obscuring your home IP? I can definitely see benifits to not leaking your home address, but otherwise the reverse proxy and wireguard tunnels don’t actually add any increased security for the extra steps. You could just host a reverse proxy at home, and any flaws Jellyfin could have in their app would still be exposed.
I’m not knocking your solution, I’m just in a similar place and considering if I want to go through the extra hurdle for a VPS if I don’t need one.
That’s basically what I do right now except I do have a domain and my ISP doesn’t restrict inbound ports like 443 so it works fine.
Just trying to sort out if I want the headache of a VPS if I don’t need it (costs, maintenance, point of failure, etc).
