I needed a way of accessing services hosted on my LAN externally.
This could have been a tricky task as my home network runs off a 5G connection with frequently changing IP address.
The Cloudflared addon for HomeAssistant is a great way to achieve this.
The primary function of Cloudflared is to make HA accessible externally via a cloudflare Argo tunnel. Installing this onto the homeassistant instance allows for DDNS to track the changing WAN IP of my LAN.
As a secondary function, this addon also allows me to configure additional tunnels for further service, therefore allowing me to use this addon as a replacement to an NGinx proxy.
