Recent questions
What are Cloudflare tunnels?
Cloudflare tunnels provide secure external access to internal services and applications, acting like a VPN without compromising firewall security or exposing WAN IP addresses.
How do Cloudflare tunnels work?
Cloudflare tunnels connect to Cloudflare's services via a fully qualified domain name, eliminating the need to expose WAN IP addresses. They allow secure HTTP connections to devices lacking secure interfaces, converting connections to HTTPS with valid certificates.
What are the advantages of Cloudflare tunnels over traditional VPN?
Cloudflare tunnels simplify external user connections to internal resources without firewall modifications. They can function with internet connections like Starlink and T-Mobile home internet, surpassing VPN capabilities.
What is needed to set up Cloudflare tunnels?
Setting up Cloudflare tunnels requires a domain name, a Cloudflare account, and a Cloudflare connector, which can be established using Docker on various platforms. Adding a domain to Cloudflare involves changing root name servers to Cloudflare's.
How can Cloudflare tunnels be secured?
To enhance security, access settings in the Zero Trust dashboard should be adjusted by setting up login methods like one-time pin and Google authentication. Applications can be protected by creating policies with include, require, and exclude rules based on email domains, geographical locations, and other criteria.

Setting up Cloudflare Connector with Docker
- A Cloudflare Connector is needed to connect and authenticate with a tunnel created in Cloudflare, maintaining an open connection for fully qualified domain names to route through Cloudflare to the internal LAN.
- Various methods exist to create the connector, including options for Windows, Mac, Debian, Red Hat, and Docker.
- Setting up a Cloudflare Connector with Ubuntu on a Synology NAS using a virtual machine is resource-intensive and inefficient.
- Docker is recommended for its lightweight nature, requiring minimal resources compared to a full virtual machine.
- Instructions for installing the connector differ based on the selected platform, with specific commands provided for Windows, Mac, Debian, Red Hat, and Docker.
- Docker is ideal for running lightweight applications, utilizing resources as needed without the overhead of a full virtual machine.
- Detailed steps are outlined for setting up the Cloudflare Connector using Docker on a Synology NAS, including pulling the Cloudflare image from the Docker registry and launching the container.
- Configuration settings, such as naming the container, enabling auto-restart, and specifying the execution command with the authentication token, are crucial for proper setup.
- Creating fully qualified domain names through Cloudflare allows external access to internal resources, with HTTPS connections and valid SSL certificates provided by Cloudflare.
- Additional services, like a Pi-hole, firewall interface, and open speed test server, can be added to the Cloudflare tunnel by configuring public host names and adjusting TLS settings as needed for secure access.
