Sharing Jellyfin (poptalk.scrubbles.tech)

Hi folks. So, I know due to a myriad of reasons I should not allow Jellyfin access to the open internet. However, in trying to switch family over from Plex, I'll need something that "just works".

How are people solving this problem? I've thought about a few solutions, like whitelisting ips (which can change of course), or setting up VPN or tail scale (but then that is more work than they will be willing to do on their side). I can even add some level of auth into my reverse proxy, but that would break Jellyfin clients.

Wondering what others have thought about for this problem

Reverse proxy with CrowdSec, which has setups specifically for Jellyfin. Docker for everything.

Now that's interesting, what is the purpose of the reverse proxy, don't you still need something exposed then?

[–] synestine@sh.itjust.works 4 points 6 hours ago

The reverse proxy is the part that's exposed. CrowdSec watches the logs for intrusion attempts like fail2ban would.

A reverse proxy saves you from having to expose your services directly and acts as a go-between.

Internet <--> Reverse Proxy <--> Service

Right, but what exactly does the reverse proxy do to stop intrusion?

[–] possiblylinux127@lemmy.zip 1 points 1 hour ago

It protects against vulnerabilities in layer 3 of the OSI model. It is the thing that gets hit from the outside while the back end is hidden away. This makes some attacks much harder.

Think of it as more modular.

I personally used Traefik, but only because I'm a masochist and it would be useful to know in IT workplace.

Traefik + CrowdSec + CowdSec Traefik Bouncer.

Traefik handles the traffic, and said traffic has to get a green light from CrowdSec + Bouncer before it can go anywhere.

The concept of CrowdSec is honestly super awesome.

Is Taefik really that good? It seems crazy complex

[–] Codilingus@sh.itjust.works 1 points 13 minutes ago

It's designed to scale. Plus it's nifty to be able to add ~3 tags to a docker container and then it's instantly online and ready to be used.

[–] Jakeroxs@sh.itjust.works 2 points 4 hours ago (1 children)

Crowdsec is what stops the intrusion.

[–] possiblylinux127@lemmy.zip 1 points 1 hour ago

Crowdsec won't protect against a security vulnerability
