A reverse proxy is what you are looking for. I recommend Caddy.
You’ll also need a domain, but they can be had for very cheap.

Another way:
Expose using caddy. Use basic auth for the web UI only. This exempts the Jellyfin app clients from basic auth that they don’t support but requires it before anyone even gets to the Jellyfin UI. This obfuscates the fact that your endpoint is even a Jellyfin end point.
Run the jellyfin in a container that only has read privileges to the videos ( make sure you can't get out to your whole NAS from there), put that behind a Cloudflaired tunnel.
It's not technically secure, but if they can't get a foothold in your network and the only thing they can access is your video catalog, that's a reasonable amount of risk.
Gotta be careful with cloudflared and media. They can block you if they detect copyrighted materials, even if it's your own DVDs. You can setup TLS certs so the traffic is at least encrypted
If your American, ripping your own DVD's still isn't legal.
Right. Which is why Cloudflared would block you if it's detected. But regardless, if for whatever reason, you ended up in court for the content you copied, the judge would probably give you a low fine. Obviously not legal advice, but the US justice system doesn't have time to care about people making digital copies of DVDs they've purchased.
It's irrelevant anyway, since none of us are just copying our own DVDs... But for legal reasons /s
Ask them to visit https://ipv4.icanhazip.com/ and give you back the number, then whitelist in your webserver, as well as your LAN/VPN range, deny rest. Explain they can only reach jellyfin from their home internet. Repeat if they get 403 forbidden after they get a new WAN IP.
That or VPN like openziti, wireguard but gets more complicated.
Perhaps (and I know I might be weird) running pangolin on something like hetzner? (Which I do)
If anyone has any tips for getting Tailscale running via Docker on my Openmediavault machine, I'm open to it. Everyone lauds it for being dead simple and I cannot for the life of me get it running on the machine it needs to be. Not sure my wife can/will handle anything more complicated.
Just read their actual documentation. You'll want to either way.
For a remote and non-technical user I would say IP whitelisting offers a decent tradeoff.
On your end you expose your jellyfin port to internet, but restrict at the router level to your user's client IP address as soon as you have it. Obviously in practice this works best if the address does not change often.
Is there a way to this with like a MAC address instead of an IP? Allowing specific devices (my parents have a Firestick that they travel with) would be pretty ideal.
Also not as ideal if their ISP uses CGNAT. Still waaay better than fully open, but you would be giving access to many households
Not at all, there's legal risk if you're hosting your blurays. Cloudflare even explicitly forbids such use. VPN or nothing imo.
Wow, Cloudflare is against piracy? Every single site I've ever seen in my life is registered with Cloudflare and uses their DNS with the exception of PTB I believe.
They have to be. They have to at least somewhat comply with laws to avoid lawsuits and fines
Oh, ok, "they have to be" in the same way my seedbox says not to download copyright material. Got it.
Not sure about that, I think it's more just that they don't want people streaming terabytes of traffic through their edge.
Well, I don't know. Cloudflare seems to be the standard, again with that one exception, and the only reason PTB has a different situation is because the founders had a connect.
Legal risk of bluray rips, as opposed to other media types?
Set up a reverse proxy with https always on. And get a good (physical) firewall, preferably something akin to opnsense, pfsense, openwrt. Exposing is always a risk, and if you do want it, you have to bear the responsibility for your own security. Keep things up to date, set up monitoring and a good logging system (Wazuh) comes to mind.
Exposure means a security risk. How you deal with that security risk is your choice.
Cloudflare and the likes forbid usage of their stuff for these things.
Cf used to have it against the rules, but it's fine now.
Ah cool, didn't know!
How does a reverse proxy helps for security? I mean, the problem here is that exposing Jellyfin on the internet is dangerous: the only way to improve security via a reverse proxy would be mTLS, but I'm not sure how it would work client side.
By setting up a reverse proxy you redirect the traffic through that specific proxy which means less open ports (basically just 80/443), less monitoring, the ability to easily put a WAF inbetween, etc.
You've got a couple benefits. If you have a domain name, and aren't advertising it publicly, then you can use the reverse proxy to point that domain to a non-standard port that Jellyfin runs on.
Security through obscurity is not good security, but it does prevent the majority of port scanning attacks. You can also use fail2ban on the reverse proxy side to try and mitigate some attacks.

😬
Secure is relative, you should be aware that jellyfin itself has security issues https://github.com/jellyfin/jellyfin/issues/5415 most of which are harmless, but at least one is fairly serious and allows people to watch your media without authentication, and adding an extra layer of authentication on the proxy would likely cause issues with clients.
That being said, if you're okay with those security issues what I would do is have a cheap VPS, connect both machines to tailscale, and have something like Caddy on the VPS to do the forwarding.
Isn’t it hilarious that the best solution to do remote streaming using the free software that people use because they don’t want to pay for a Plex subscription or one-off cost is to pay for at least one subscription, maybe more?
It’s almost like the reason Plex charge money is because it’s not free to do.
Just leaving this here
Now, let's address this clearly once and for all. What is possible is unauthenticated streaming. Each item in a Jellyfin library has a UUID generated which is based on a checksum of the file path. So, theoretically, if someone knows your exact media paths, they could calculate the item IDs, and then use that ItemID to initiate an unauthenticated stream of the media. As far as we know this has never actually been seen in the wild. This does not affect anything else - all other configuration/management endpoints are behind user authentication. Is this suboptimal? Yes. Is this a massive red-flag security risk that actively exposes your data to the Internet? No.

It really seems overblown of an issue...
Except most people have almost the same structure because of media organizers like radarr/sonarr. At the very least they should hide that behind a setting to not require auth (since the header should be there for most clients) so only people running an old client would be affected. They could also add an extra salt to that hash or something similar.
I agree, it's not critical, but it shouldn't be hand waved either. And like I said, security is relative, I would argue for most people this is fine, but I still think this should be taken more seriously.
At the very minimum stick a reverse proxy in front like caddy, nginx, or Traefik. Then have some middleware like crowdsec to inspect what's going on. Then whitelist the IP or the country IP block.
There is much more but those would be the bare minimum.
