    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.

    Don't even need a static IP. Dyndns is enough.

      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.

        I already host multiple services via caddy as my reverse proxy. Jellyfin, I am worried about authentication. How do you secure it?

        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 😐

            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 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 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?

                    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.

                      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 crowdsec

                                    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...

                                        I already host multiple services via caddy as my reverse proxy. Jellyfin, I am worried about authentication. How do you secure it?

                                        Wireguard (or tailscale) would be best here.

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