How to secure Jellyfin hosted over the internet?
-
I use Tailscale right now. Which, in fairness, I didn't state in the post. However, I was hoping to share it more similarly to how I used to with Plex. But, it would appear, I would have to share it through Tailscale only at this point.
Right now none of the native clients support SSO. It is a frequently requested feature but, unfortunately, it doesn't look like it will be implemented any time soon. As with many OSS projects it is probably a case of "you want it, you build it" - but nobody has actually stepped up.

I am using tailscale but I went a little further to let my family log in with their Gmail( they will not make any account for 1 million dollars)
Tailscale funneled
Jellyfin
Keycloak (adminless)Private Tailscale
Keycloak admin
Postgres dBI hook up jellyfin to Keycloak (adminless) using the sso plugin. And hook Keycloak up (using the private instance) to use Google as an identity provider with a private app.
SSO plugin is good to know about. Does that address any of the issues with security that someone was previously talking about?

This is how I found out Google harvests the URLs I visit through Chrome.
Got google bots trying to crawl deep links into a domain that I hadn't published anywhere.
This is true, and is why I annoyingly have to keep robots.txt on my unpublished domains. Google does honor them for the most part, for now.

I already host multiple services via caddy as my reverse proxy. Jellyfin, I am worried about authentication. How do you secure it?
setup a WAF appliance and forward traffic through it to your current installation.

Right, but I have wireguard on my opnsense. So when I want to reach https://jellyfin.example.com/ , if I am at home, it goes phone -> DNS -> proxy -> jellyfin (on the same network). If I am connected to the VPN, it goes from phone -> internet -> opnsense public ip -> wireguard subnet -> local subnet -> DNS -> proxy -> jellyfin. I see some unneeded extra steps here... Am I wrong?
Oh yeah, there'll be some overhead if you're running Wireguard on a router. Hitting your router's public IP won't go out to the internet though - the router will recognize that it's its IP.
It's common to run Wireguard on every computer/phone/tablet/etc rather than just on the router, since this takes advantage of its peer-to-peer nature. Tailscale makes it a lot easier to configure it this way though - it's a bit of work for vanilla Wireguard.

That reminds me ... another annoying thing Google did was list my private jellyfin instance as a "deceptive site"
A common issue it seems.

https://codeberg.org/skjalli/jellyfin-vps-setup here you go, took me longer than expected and I hope it's helpful, might contain a few errors since I had to remove some settings but I guess this should work.
This is honestly awesome! I was thinking about a similar setup for a long time but wasn’t sure how to do this exactly, this seems exactly like the setup I was looking for. Thank you!

I'd say it's nearly as secure as basic authentication. If you restrict deletion to admin users and use role (or group) based auth to restrict that jellyfin admin ability to people with strong passwords in keycloak, i think you are good. Still the only risk is people could delete your media if an adminusers gmail is hacked.

I use good ol' obscurity. My reverse proxy requires that the correct subdomain is used to access any service that I host and my domain has a wildcard entry. So if you access asdf.example.com you get an error, the same for directly accessing my ip, but going to jellyfin.example.com works.
And since i don't post my valid urls anywhere no web-scraper can find them.
This filters out 99% of bots and the rest are handled using authelia and crowdsecThat’s not how web scrappers work lol. No such thing as obscurity except for humans

You're welcome, happy that I can help. I also just updated it a bit. In case you find any issues or have questions please let me know. It was mostly trial and error until it ran..

I don't think I've ever encountered what you say... I use WG it to access a network, not a device. I have a few dozen devices, physical and virtual, why should I set up wg on all of them? Tailscale, maybe, it's a different story, but I prefer to "self host" and not rely on a 3rd party provider. Wireguard was relatively easy to set up too, a few years ago... and in the meantime, if I need to add a new client, it's a two minute job.

It seems to that it works. I don't get any web-scrapers hitting anything but my main domain. I can't find any of my subdomains on google.
Please tell me how you believe that it works. Maybe i overlooked something...

Wireguard (or tailscale) would be best here.

I set mine up with Authelia 2FA and restricted media deletion to one user: The administrator.
All others arent allowed to delete. Not even me. -

They did that with most of my subdomains

This filters out 99% of bots and the rest are handled using authelia and crowdsecIf you're using jellyfin as the url, that's an easily guessable name, however if you use random words not related to what's being hosted chances are less, e.g. salmon.example.com . Also ideally your server should reply with a 200 to * subdomains so scrappers can't tell valid from invalid domains. Also also, ideally it also sends some random data on each of those so they don't look exactly the same. But that's approaching paranoid levels of security.

Unsurprising, but still shitty. Par for the course for the company these days.

My understanding is that scrappers check every domain and subdomain. You’re making it harder but not impossible. Everything gets scrapped
It would be better if you also did IP whitelisting, rate limiting to prevent bots, bot detection via cloudflare or something similar, etc.

So i’ve been trying to set this up this exact thing for the past few weeks - tried all manner of different Nginx/Tailscale/VPS/Traefik/Wireguard/Authelia combos, but to no avail
I was lost in the maze
However, I realised that it was literally as simple as setting up a CloudFlare Tunnel on my particular local network I wanted exposed (in my case, the Docker network that runs the JellyFin container) and then linking that domain/ip:port within CloudFlare’s Zero Trust dashboard
And you can even set up what looks like pretty robust authentication (2FA, limited to only certain emails, etc)
Not sure what your use case is, but as mine is shared with only me and my partner, this worked like a charm

I'm pretty sure that using Jellyfin over Cloudflare tunnels is against their TOS, just FYI. I'm trying to figure out an alternative myself right now because of that.
