setup a WAF appliance and forward traffic through it to your current installation.
WAF??
web application firewall.
think of it like an intelligent firewall proxy that can take action against perceived threats like injection attacks or timed attacks. some can also help fight against DDOS when integrated with an actual firewall upstream.
What I used to do was: I put jellyfin behind an nginx reverse proxy, on a separate vhost (so on a unique domain). Then I added basic authentication (a htpasswd file) with an unguessable password on the whole domain. Then I added geoip firewall rules so that port 443 was only reachable from the country I was in. I live in small country, so this significantly limits exposure.
Downside of this approach: basic auth is annoying. The jellyfin client doesn't like it ... so I had to use a browser to stream.
Nowadays, I put all my services behind a wireguard VPN and I expose nothing else. Only issue I've had is when I was on vacation in a bnb and they used the same IP range as my home network :-|
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 crowdsec
If 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.
That’s not how web scrappers work lol. No such thing as obscurity except for humans
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...
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.
Are you using HTTPS? It's highly likely that your domains/certificates are being logged for certificate transparency. Unless you're using wildcard domains, it's very easy to enumerate your sub-domains.
And since i don't post my valid urls anywhere no web-scraper can find them
You would ah... be surprised. My urls aren't published anywhere and I currently have 4 active decisions and over 300 alerts from crowdsec.
It's true none of those threat actors know my valid subdomains, but that doesn't mean they don't know I'm there.
Of course i get a bunch of scanners hitting ports 80 and 443. But if they don't use the correct domain they all end up on an Nginx server hosting a static error page. Not much they can do there
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.
That reminds me ... another annoying thing Google did was list my private jellyfin instance as a "deceptive site", after it had uninvitedly crawled it.
A common issue it seems.
Unsurprising, but still shitty. Par for the course for the company these days.
They did that with most of my subdomains
Whats your setup? I just Ngnix Proxy Manager, Jellyfin etc in Docker. Modify ufw rules and also install this on the server (linux) https://github.com/friendly-bits/geoip-shell
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 dB
I 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?
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.
Will say it's not as secure as restricting access to vpn, you could be brute forced. Frankly it would be preferable to set up rate limiting, but that was a bridge too far for me
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.
Is it just you that uses it, or do friends and family use it too?
The best way to secure it is to use a VPN like Tailscale, which avoids having to expose it to the public internet.
This is what I do for our security cameras. My wife installed Tailscale on her laptop and phone, created an account, and I added her to my Tailnet. I created a home screen icon for the Blue Iris web UI on her phone and mentioned to her, "if the cameras don't load, open Tailscale and make sure it's connected". Works great - she hasn't complained about anything at all.
If you use Tailscale for everything, there's no need to have a reverse proxy. If you use Unraid, version 7 added the ability to add individual Docker containers to the Tailnet, so each one can have a separate Tailscale IP and subdomain, and thus all of them can run on port 80.
For web access, stick it behind a reverse proxy and use something like Authentik/Authelia/SSO provider of your choice to secure it.
For full access including native clients, set up a VPN.
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.
My setup: Locally (all in docker):
VPS (Oracle Cloud free tier, also everything in docker):
Usernames are not shown in the frontend and have to be entered. Passwords are generated by a password manager and can't be changed by the user.
So my clients just get the URL of my reverse proxy and can access the read only JF through my Wireguard tunnel. Didn't have to open any ports on my side. If someone is interested I can share the docker compose files later.
Edit: Here the link to the setup description. Please tell me if something is not clear or you find an error. https://codeberg.org/skjalli/jellyfin-vps-setup
I am interested in your docker compose
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!
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..
Will share this evening after work.
Tailscale is awesome. Alternatively if you're more technically inclined you can make your own wireguard tailscale and all you need is to get a static IP for your home network. Wireguard will always be safer than each individual service.
all you need is to get a static IP for your home network
Don't even need a static IP. Dyndns is enough.
Unless you're behind cgnat and without ipv6 support.
cgnat
Ew
Love tailscale. The only issue I had with it is making it play nice with my local, daily driver VPN. Got it worked out tho. So, now everything is jippity jippity.
Use a VPN like Tailscale
I use fail2ban to ban IPs that fall to login and also IPs that perform common scans in the reverse proxy
also have jellyfin disable the account after a number of failed logins.
I have another site on a different port that sits behind basic auth and adds the IP to a short ipset whitelist.
So first I have to auth into that site with basic auth, then I load jellyfin on the other port.
I don't understand how that isn't widely deployed. I call it poor man's Zero Trust.
I mean I'd rather jellyfin fix the bug and let me just put that behind basic auth
