Jellyfin server, YouFibre, "CGNAT" issue?

[ssmacc]

Hello All,

I've recently got YouFibre 2GB and would like to set up a Jellyfin server I can access remotely...I've had a few goes at this without success...

I've followed this guide and it fall overs when I try to connect to the DuckDNS service I set up...

I think (stress think) this is due to a "CGNAT" issue? (again, amateur using words I don't understand )

My question is would paying for a Static IP with YouFibre fix this?

If not, is there something I'm missing a better way to get a Jellyfin server to be accessible remotely ?

Any advice appreciated.

Cheers,

Have you tried Tailscale?

Yeah the static IP will fix it but there's options like Tailscale as mentioned which is what I'm going to try setting up when I get the time.

Youfibre will charge 5pm extra for the static.

Thanks, I'll look into "Tailscale" over the next couple of days...

I use Plex a lot (at home) but the bitrate is dreadful externally without a Plex pass and that seems silly money now...

If you stumble across any decent guides feel free to post!

If the places you want to access it remotely have IPv6-enabled connections then you can get this working without buying anything

I noticed the bitrate being awful recently on my setup and fixing the port forwarding so it could stream directly resolved it without paying for a Plex pass. You’d also need a public IP for this though

YouFibre do utilise CGNAT on non-static connections so as identified, you aren't going to do this without "something" extra added to the mix.
Personally - I pay the £5 for a static, I consider it essential if you fettle, tinker and tweak. If you haven't already, create a plex account anyway, usually around black friday they will send out an email with a pass offer which may be useful for you. I think I picked mine up for about £70 about 10 years ago.
Tailscale will work if you want to do the VPN thing but it is another layer of "stuff" needed on top of what you have and not easily shared should you want to (imagine talking a non techy family member thorugh bringing a vpn up and down when they want to access your movies)

Ultimately you know your own use case best to pick the right option, I would personally just swallow the £5 a month and not have the complication of a VPN (well actually I run a Wireguard server from my firewall for when I'm out so multiple benefits to the static).

Thanks for the response...I think I'm going to pay the £5, once I have a static IP is it just a case of following the guide (original post), or is there another guide you'd recommend?

(and thanks all!)

If you get a static IP, then you're no longer on CGNAT, so the guide should work fine (technically you won't need duckdns, as you could manually set your IP & it won't change, but it's probably simpler to just follow the guide).

I had similar setup with my previous ISP, now I'm on a CGNAT ISP, as you've found out, that doesn't work. I decided to go down the route of using cloudflare zerotrust tunnels for my plex server instead. They're free to use & so far has worked great (but took a bit of fidling to setup & you need your own domain name (mine cost ~£5/year)). The general view on this, is it's against cloudflare's ToS, however unless you're selling access & have a lot of users connecting, with a lot of traffic, they don't seem to care.

I haven't watched the video in your OP but it should just be a case of follow it and instead of the duckdns you enter your shiny new WAN IP.

A "nice" to have would be to register a .uk domain or similar for £4 a year and point a record to your IP in case you move ISP in a few years or just to make it more memorable so instead of 1.2.3.4 you can point stuff at my.domain.uk
