What’s your go too (secure) method for casting over the internet with a Jellyfin server.
I’m wondering what to use and I’m pretty beginner at this
Jellyfin isn't secure and is full of holes.
That said, here's how to host it anyway.
If you aren't using Tailscale, make your VPS your main hub for whatever you choose, pihole, wg-easy, etc. Connect the proxy to Jellyfin through your chosen tunnel, with ssl, Caddy makes it easy.
Since Jellyfin isn't exactly secure, secure it. Give it its own user and make sure your media isn't writable by the user. Inconvenient for deleting movies in the app, but better for security.
more...
Use fail2ban to stop intruders after failed login attempts, you can force fail2ban to listen in on jellyfin's host for failures and block ips automatically.
More!
Use Anubis and yes, I can confirm Anubis doesn't intrude Jellyfin connectivity and just works, connect it to fail2ban and you can cook your own ddos protection.
MORE!
SELinux. Lock Jellyfin down. Lock the system down. It's work but it's worth it.
I SAID MORE!
There's a GeoIP blocking plugin for Caddy that you can use to limit Jellyfin's access to your city, state, hemisphere, etc. You can also look into whitelisting in Caddy if everyone's IP is static. If not, ddns-server and a script to update Caddy every round? It can get deep.
Again, don't do any of this and just use Jellyfin over wireguard like everyone else does(they don't).
Wow, a "for dummies" guide for doing all this would be great 😊 know of any?
If you aren’t already familiarized with the Docker Engine - you can use Play With Docker to fiddle around, spin up a container or two using the docker run command, once you get comfortable with the command structure you can move into Docker Compose which makes handling multiple containers easy using .yml files.
Once you’re comfortable with compose I suggest working into Reverse Proxying with something like SWAG or Traefik which let you put an domain behind the IP, ssl certificates and offer plugins that give you more control on how requests are handled.
There really is no “guide for dummies” here, you’ve got to rely on the documentation provided by these services.
I just expose my local machine to the internet, unsecured
Thanks stranger over the internet seems like the best option.
Nginx in front of it, open ports for https (and ssh), nothing more. Let's encrypt certificate and you're good to go.
I would not publicly expose ssh. Your home IP will get scanned all the time and external machines will try to connect to your ssh port.
I host it publicly accessible behind a proper firewall and reverse proxy setup.
If you are only ever using Jellyfin from your own, wireguard configured phone, then that's great; but there's nothing wrong with hosting Jellyfin publicly.
I think one of these days I need to make a "myth-busting" post about this topic.
Please do so, it'll be very useful
Same for me. But according to everyone I should be destroyed.
I access it through a reverse proxy (nginx). I guess the only weak point is if someone finds out the domain for it and starts spamming the login screen. But I've restricted access to the domain for most of the world anyway. Wireguard would probably be more secure but its not always possible if like on vacation and want to use it on the TV there..
If it’s just so you personally can access it away from home, use tailscale. Less risky than running a publicly exposed server.
I use a wire guard tunnel into my Fritz box and from there I just log in because I'm in my local network.
Tailscale with self hosted headscale
Wireguard VPN to my fritzbox lets me access my jellyfin.
for me the easiest option was to set up tailscale on the server or network where jellyfin runs and then on the client/router where you want to watch the stream.
If you’re a beginner and you’re looking for the most secure way with least amount of effort, just VPN into your home network using something like WireGuard, or use an off the shelf mesh vpn like Tailscale to connect directly to your JF server. You can give access to your VPN to other people to use. Tailscale would be the easiest to do this with, but if you want to go full self-hosted you can do it with WireGuard if you’re willing to put in a little extra leg work.
What I’ve done in the past is run a reverse proxy on a cloud VPS and tunnel that to the JF server. The cloud VPS acts as a reverse proxy and a web application firewall which blocks common exploits, failed connection attempts etc. you can take it one step beyond that if you want people to authenticate BEFORE they reach your server by using an oauth provider and whatever forward Auth your reverse proxy software supports.
I see everyone in this thread recommending a VPN or reverse proxy for accessing Jellyfin from outside the LAN. While I generally agree, I don't see a realistic risk in exposing Jellyfin directly to the internet. ~~It supports HTTPS and certificates nowadays, so there’s no need for outside SSL termination anymore.~~ (See Edit 2)
In my setup, which I've been running for some time, I've port-forwarded only Jellyfin's HTTPS port to eliminate the possibility of someone ending up on pure HTTP and sending credentials unencrypted. I've also changed the Jellyfin's default port to a non-standard one to avoid basic port-scanning bots spamming login attempts. I fully understand that this falls into the security through obscurity category, but no harm in it either.
Anyone wanna yell at me for being an idiot and doing everything wrong? I'm genuinely curious, as the sentiment online seems to be that at least a reverse proxy is almost mandatory for this kind of setup, and I'm not entirely sure why.
Edit: Thank you everyone for your responses. While I don't agree with everything, the new insight is appreciated.
Edit 2: I've been informed that infact the support for HTTPS will be removed in a future version. From v10.11 release notes:
Deprecation Notice: Jellyfin’s internal handling of TLS/SSL certificates and configuration in the web server will be removed in a future version. No changes to the current system have been made in 10.11, however future versions will remove the current system and instead will provide advanced instructions to configure the Kestrel webserver directly for this relatively niche usecase. We strongly advise anyone using the current TLS options to use a Reverse Proxy for TLS termination instead if at all possible, as this provides a number of benefits
Anyone wanna yell at me for being an idiot and doing everything wrong?
Not yell, but: Jellyfin is dropping HTTPS support with a future update so you might want to read up on reverse proxies before then.
Additionally, you might want to check if Shodan has your Jellyfin instance listed: https://www.shodan.io/
It feels like everything is a tradeoff and I think a setup like this reduces the complexity for people you share with.
If you added fail2ban along with alert email/notifications you could have a chance to react if you were ever targeted for a brute force attempt. Jellyfin docs talk about setting this up for anyone interested.
Blocking IP segments based on geography of countries you don't expect connections from adds the cost of a VPN for malicious actors in those areas.
Giving Jellyfin its own VLAN on your network could help limit exposure to your other services and devices if you experience a 0day or are otherwise compromised.
Fail2ban isn't going to help you when jellyfin has vulnerable endpoints that need no authentication at all.
Your comment got me looking through the jellyfin github issues. Are the bugs listed for unauthenticated endpoints what you're referencing? It looks like the 7 open mention being able to view information about the jellyfin instance or view the media itself. But this is just what was commented as possible, there could be more possibilities especially if combined with other vulnerabilities.
Now realizing there are parts of Jellyfin that are known to be accessible without authentication, I'm thinking Fail2ban is going to do less but unless there are ways to do injection with the known bugs/a new 0day they will still need to brute force a password to be able to make changes. I'm curious if there is anything I'm overlooking.
Nah, setting non-standard ports is sound advice in security circles.
People misunderstand the "no security through obscurity" phrase. If you build security as a chain, where the chain is only as good as the weakest link, then it's bad. But if you build security in layers, like a castle, then it can only help. It's OK for a layer to be weak when there are other layers behind it.
Even better, non-standard ports will make 99% of threats go away. They automate scans that are just looking for anything they can break. If they don't see the open ports, they move on. Won't stop a determined attacker, of course, but that's what other layers are for.
As long as there's real security otherwise (TLS, good passwords, etc), it's fine.
If anyone says "that's a false sense of security", ignore them. They've replaced thinking with a cliche.
It's difficult to say exactly what all a reverse proxy adds to the security conversation for a handful of reasons, so I won't touch on that, but the realistic risk of exposing your jellyfin instance to the internet is about the same as handing your jellyfin api over to every stranger globally without giving them your user account or password and letting them do whatever they'd like for as long as they'd like. This means any undiscovered or unintentional vulnerability in the api implementation could easily allow for security bypass or full rce (remote code execution, real examples of this can be found by looking at the history of WordPress), but by siloing it behind a vpn you're far far far more secure because the internet at large cannot access the apis even if there is a known vulnerability. I'm not saying exposing jellyfin to the raw web is so risky it shouldn't be done, but don't buy into the misconception that it's even nearly as secure as running a vpn. They're entirely different classes of security posture and it should be acknowledged that if you don't have actual use for internet level access to jellyfin (external users, etc, etc) a vpn like tailscale or zero tier is 100% best practice.
Jellyfin has a whole host of unresolved and unmitigated security vulnerabilities that make exposing it to the internet. A pretty poor choice.
And which one of those are actually vulnerabilities that are exploitable? First, yes ofc unauthenticated endpoints should be fixed, but with those there is no real damage to be done.
If you know the media path then you can request a playback, and if you get the user ids then you can get all users. That's more or less it.
Good? No. But far from making it a poor choice exposing it.
Full guide to setting up Jellyfin with Reverse Proxy using Caddy and DuckDNS
I followed this video and modified some things like ports
I rent a cheap $5/mo VPS and use it to run a wireguard server with wgeasy and nginx proxy manager. Everything else runs on my home server connected by wireguard.
I used to do all the things mentioned here. Now, I just use Wireguard. If a family member wants to use a service, they need Wireguard. If they don't want to install it, they dont get the service.
Tailscale + Caddy (automatic certificates FTW).
VPN or Tailscale
“Technically” my jellyfin is exposed to the internet however, I have Fail2Ban setup blocking every public IP and only whitelisting IP’s that I’ve verified.
I use GeoBlock for the services I want exposed to the internet however, I should also setup Authelia or something along those lines for further verification.
Reverse proxy is Traefik.
My go to secure method is just putting it behind Cloudflare so people can’t see my IP, same as every other service. Nobody is gonna bother wasting time hacking into your home server in the hopes that your media library isn’t shit, when they can just pirate any media they want to watch themselves with no effort.
Nobody is gonna bother wasting time hacking into your home server
They absolutely will lol. It’s happening to you right now in fact. It’s not to consume your media, it’s just a matter of course when you expose something to the internet publicly.
No, people are probing it right now. But looking at the logs, nobody has ever made it through. And I run a pretty basic setup, just Cloudflare and Authelia hooking into an LDAP server, which powers Jellyfin. Somebody who invests a little more time than me is probably a lot safer. Tailscale is nice, but it’s overkill for most people, and the majority of setups I see posted here are secure enough to stop any random scanning that happens across them, if not dedicated attention.
