Kind of a quick off the cuff question.... but is it difficult to get a docker hosted jellyfin server accessible outside of lan safely?

I have tailscale and a VPN I can use for my own devices but would like to be able to access it safely without needing those.

Stick with the VPN. No point in exposing more services with possible security vulnerabilities.

I love Jellyfin but I would absolutely not make it accessible over the public internet. A VPN is the way to go.

Yeah I'm thinking maybe just have family sign up for tailscale.

Why not just run your own WireGuard instance? I have a pivpn vm for it and it works great. You could also just put jellyfin behind a TLS terminating reverse proxy.

Sounds like a pain to get non technical family members to use. If you're willing to break the non web app you could always put it behind an authenticating proxy (which is what I do for myself outside of VPN, setting up a VPN on a phone is obnoxious and I only look at metadata anyway on my phone)

Why not just run your own WireGuard instance?

CGNAT is a big reason.

Or headscale, works like a charm

Yep, that way you can set ACLs, you they can only access the jellyfin ports + the ports you allow them to.

Also, tailacale DNS.

The fact that tailscale has google/apple/etc logon integration will also help.

Oof, that's bad... And lazy

[–] [email protected] 5 points 1 year ago

Unfortunately a lot of these issues are architectural issues inherited from Emby

If you are not behind a CGNAT, it should be as easy as opening the necessary ports.

I have a reverse proxy running in ports 80, 443 and can safely access Jellyfin on a subdomain without issues from outside my LAN.

Acronyms, initialisms, abbreviations, contractions, and other phrases which expand to something larger, that I've seen in this thread:

Fewer Letters More Letters
CGNAT Carrier-Grade NAT
DNS Domain Name Service/System
NAT Network Address Translation
SSL Secure Sockets Layer, for transparent encryption
TLS Transport Layer Security, supersedes SSL
VPN Virtual Private Network

5 acronyms in this thread; the most compressed thread commented on today has 8 acronyms.

To get it outside the LAN, you just need to forward the port it uses in your router. Example 8096 for regular http requests. I would highly recommend getting at least a reverse proxy with an SSL cert.

[–] [email protected] 2 points 1 year ago

Depends on your definition of safe.

If you do a public port forward and set up basic security and proper SSL its safe from the majority of people.

[–] [email protected] 1 points 1 year ago

You can but it will cause security issues. You will need to buy a domain and setup a SSL proxy with https to proxy traffic in. After than I would lock down you firewall rules and make sure that a compromise can't escape the isolated environment.

Also make sure you docker container is hardened against excaping as it will improve security when a security hole is discovered in jellyfin
