Moving from Cloudflare tunnels for media streaming, first plan didn't work out due to double NAT

Submitted ⁨⁨3⁩ ⁨weeks⁩ ago⁩ by ⁨chriscrutch@lemm.ee⁩ to ⁨selfhosted@lemmy.world⁩

I have several services on my home server, most of which I access using Tailscale, and it works great. I had a couple services on Cloudflare tunnels in order to access them from devices that I can’t put Tailscale on.

Plex is going to start charging for remote access. So I figured now would be the time to migrate to Jellyfin. But using Jellyfin on Cloudflare tunnels is against their TOS. I have a Roku TV at a remote location that I use to watch Plex. I won’t be able to do that anymore. And I can’t put Tailscale on it to serve Jellyfin that way.

I was going to set up Nginx Proxy Manager to use my domain name for Jellyfin so I didn’t have to use Cloudflare tunnels. But in setting that up I found out that my ISP is double NATting me, and I haven’t been able to find a way around it.

So I’m left with two options: 1) buy Plex Pass so I can continue to stream remotely; or 2) get a VPS, run Tailscale and NPM on it and switch to Jellyfin.

I’m looking for a sanity check to make sure the VPS thing would work the way I think it would. If it’s running Tailscale then the double NAT would be a non-issue, correct? Is there another option that I haven’t thought of yet? Which of the two options would you choose?

Do not. I repeat do not expose Jellyfin to the internet. It has too many security issues to be direct accessible from the internet.

I use Jellyfin and only access it over WireGuard. I have a mesh setup between the routers at a few family members houses.

If you have absolutely no other way then to expose it to the internet you need to make sure that you whitelist only the approved IPs in your VPS firewall and block everything else.

  I keep hearing claims that it’s not secure enough to be exposed on the Internet, but I can’t seem to find anything about unauthenticated vulnerabilities. It’s got a fair amount of CVEs but they all seem to affect when you’re an already authenticated user, mainly to XSS an admin as a regular user or the likes.
  
  It’s written in C#, and publicly all you can do is pretty much attempt to log in, this feels like it should be pretty sane compared to some other PHP crap I run.
  
  Do you have any examples of previous exploits or anything else to be concerned about?

  I don’t really agree with you here. If you take the time to set things up properly. And prepaid for IF something would happen. Your fine. Been running a exposed jellyfin server for years now. Never hat a security issue. And even if I would not much harm could be done anyway due to how it is setup.

  Thanks for mentioning that. I’ll have to look into it. If I could install Tailscale on a RokuTV I’d absolutely run it that way.

    I haven’t seen no one mention it yet but you could simply buy a Rasp Pi and use it as a subnet router for your Tailnet.
    
    It’s how I set up a family members Jellyfin/NAS/etc which I can access all their devices by local IP address, and you could do for your Roku too?

  you can add authentic/authelia with keys for login and it should be fine

There’s no reason your media server needs to be directly exposed to the public internet. Use Tailscale. Get everyone that uses it to sign up for a Tailscale account, and add them all to your Tailnet.

Tailscale will perform better than any tunnel because it’s a direct connection between the two peers - it’s not relaying through an intermediary server like a Cloudflare tunnel would.

  Really no reason. Hmm how do I get a Roku to watch? Or get other people to watch stuff on it.

  I love Tailscale as well and it works flawlessly for everything I’ve ever used it for. However, I can’t install Tailscale on the Roku TV that sits remotely from my server. That’s the whole reason I’m looking for a different way.

    Have you read into subnet routers? Tailscale subnet routers

  Can tail scale be setup on tvs and game consoles and such? Or maybe on routers?

get a VPS, run Tailscale and NPM on it and switch to Jellyfin

Keep in mind that VPSs will charge for bandwidth, which adds up quickly when you’re streaming.

One suggestion I haven’t seen mentioned is contacting your ISP. Sometimes you can get a dedicated IP, although you might have to pay for it.

Alternatively you might just break down and pay for Plex Pass. I know that goes against the Lemmy philosophy to the very core, but for all its issues, Plex is still way ahead of Jellyfin in terms of features, UI/UX, etc. Jellyfin will get there, and I’m ready to switch the day that Plex becomes unusable, but that hasn’t happened yet.

  Most VPSes I use offer a slower (200mbps) connection without a data cap.

Maybe something worth a shot is a direct Wireguard server/client connection. While I don’t know how it works with double NAT (wireguard client with double nat) making your server act as a direct tunnel would solve all your issues.

Access your services from everywhere without middleman.

IIR, tailscale uses wireguard under the hood and you’re already hosting things on your home server, so maybe this could be worth a try :) !

Wasn’t it brought up last week ina thread about Plex charging that it is NOT against cloudflare TOS anymore?

Maybe using a tailscale funnel would be a good option for you? I use one for a webdav setup to get around CF’s 100mb limit on uploads when clients won’t chunk their data properly. It was fairly easy to set up and works perfectly.

I was just in you exact Situation with my jellyfin homeserver. I was using Tailscale for a while, but ran into a problem: my new server is really bad at encoding so I can only use directplay, which uses more bandwith than the tailscale relay servers can give.

The problem with tailscale is, I basically only ever use the relay servers because my home is cgnat and most of the time when I want to stream outside of home I am on mobile data with cgnat or at college (restrictive firewall).

My solution which I implemented last weekend was to buy the cheapest vps I could get from my trusted provider and harden it and install nginx proxy manager and tailscale. With that I can make a direct (no relay server) connection to my homeserver and proxy jellyfin to a piblic domain.

I am still figuring out how to secure jellyfin, but I have also seen some comments that jellyfin is secure by default and therefore ok to have exposed.

My understanding is that Jellyfin should be fine as long as you don’t serve it over the CDN (ie, disable caching for it)

Tailscale funnel is a vqlid option too
