Self-hosting guides for UK broadband
Reach your home server from anywhere
Step‑by‑step guides for opening Home Assistant, Jellyfin, Plex, Nextcloud and friends to the outside world – safely – on UK broadband. Each one ends with a working address, a valid HTTPS certificate and a way to check it from outside.
Start here Am I behind CGNAT?
01Check your connection
Port forwarding only works with a real public IP address. Many UK full‑fibre and 4G/5G providers use CGNAT. Find out in two minutes.
03Give it a name
A name such as home.yourname.uk.app follows your changing IP with dynamic DNS and gets a proper certificate. HTTPS set‑up.
A name for your next idea
Give your website, home server or next project a memorable address: yourname.uk.app. Choose your name and check availability before registering.
How these guides are written
Every guide is written by hand for one product and checked against that vendor’s current documentation, with the version we checked printed at the top. We say plainly when exposing something is a bad idea – Proxmox’s admin panel and Pi‑hole’s DNS port are two examples – and show the safer route instead.
The guides assume UK broadband: BT, Sky and Virgin Media hubs, full‑fibre altnets that use CGNAT, and the .app rule that browsers only ever connect over HTTPS. You don’t need a uk.app name to follow them, though the dynamic DNS steps use it as the example.
