Feel free to use the template below to get things going. If you want to ensure that the tunnel starts on boot and runs in the background, we need to make a custom ingress config file. If you head over to your domain name, we should find that it has now been exposed to the world. Again, you just need to replace with your tunnel name and with the port of the service you which to expose. To ensure that things are running smoothly, we can perform a test run by exposing a local service running on our machine. You’ll be able to find this in your DNS CNAME records against the domain you just used above. ![]() Make a note of this as we’ll need it later. This can be done with the following where we replace with the name we used previously and with the specific domain (provided it is a domain within our DNS records).Īt this stage, you should get a UUID. Now that we’ve created the tunnel, we need to route the tunnel to the domain name we which to host our service on. You can create as many or as little as you want! There’s no limit to how many tunnels you can have with Cloudflare.Ĭloudflared tunnel create Step 4: Route a Tunnel Just run the following and replace with the name you wish to address your tunnel. Step 3: Create a TunnelĬreating a tunnel is really easy. This will allow you to select the domain you which to use tunnels with. Once it has been updated, we need to associate cloudflared with our account.Īfter running this you’ll be prompted to login into your account with a URL generated by cloudflared. Step 2: Configure cloudflaredīefore we start creating tunnels, we need to make sure that we’re running the latest version of cloudflared. Click here for the full releases and select b. Tar -xvzf cloudflared-stable-linux-arm.tgzĮDIT: Cloudflare now support ARM64 binaries. This can be done with the following commands. If you plan on using a Raspberry Pi, you will need to download the ARM-based binaries from this link. The installation process is fairly straightforward so I won’t be covering this here. To get thing going, you will need to download and install the latest cloudflared package from here. This can be done using the your domain registrar’s control panel. If you’ve not done so already, make sure you set your domain nameservers to the ones used by Cloudflare. How to create a tunnel Step 0: Intergrate domain with Cloudflare ![]() Much like the Wireguard solution mentioned earlier, Cloudflare tunnels use secure, outward connecting tunnels meaning that it is possible to expose services (such as a web server on a Raspberry Pi within your home network) to the rest of the world without putting your internal network at risk by modifying your firewall settings. The benefits of this service is that its secure, easy to setup and it free! Because Cloudflare is so well known and has a good reputation, it’s fair to say that you’re in safe hands. Introducing Cloudflare TunnelsĬloudflare Tunnels is a feature provided by the Cloudflare DNS service. What if I told you there was an easier and more secure way of doing things which is both free and secure at the same time. While this solution does cost you a little bit of money, it also involves setting up a WireGuard VPN which isn’t exactly straightforward. One way to get round this would be to set up a public facing server with a static IP address (you can do this with DigitalOcean, Vultra, Linode, etc) and to expose services using WireGuard (to connect your servers) and a reverse proxy (to route traffic to the right service) such as nginx. Problem 2: depending on your ISP, your external IP may change from time to time meaning that you’ll have to periodlicly update your DNS records to point your domain to the right IP address. Problem 1: your external IP address will be publically visible to the internet meaning that people could geolocate and collect information about you. This involves opening up your firewall by forwarding ports 80 (HTTP) and 443 (HTTPS) to a dedicated machine on your network. If you’ve ever self-hosted services on your local network and wanted to expose them to the world, you would know that this is not a straightforward matter.
