is a virtual/non-existent domain, that is only used internally when you make CName's pointing to your tunnel and other references. You can very easily make an Application policy to protect your tunnel and limit it to only specific emails or other options. You can use the Cloudflare Teams Dash under "Access", "Tunnels" to see a good view of each tunnel you have, what routes it has, uptime/connections it has, and all other relevant information.Ĭloudflare for Teams/Cloudflare Access has a generous free plan you can use as well, for up to 50 people, using Google (or a ton of other sso options) for auth. They recommend using their own load-balancing product along with tunnels for this. Cloudflare does not recommend doing this for load-balancing, and makes no guarantee about which connection is chosen. Cloudflare says each connection can handled hundreds or thousands of requests at one time.Įach Tunnel supports up to 100 connections, you can launch more cloudflared replicas/instances for reliability. Cloudflare says it connections to multiple machines in case one crashes/reboots, it can use the other connections.Įach individual connection to Cloudflare is not limited to one user request at a time. You may have noticed, when your tunnel starts up, it makes multiple connections. With any luck, it all worked, and your Cloudflare Tunnel is now all set up, running as a service, automatically starting on reboots, and working well! Test out your tunnel by visting the hostname you routed it to. deb install (Ubuntu, Linux Mint, Debian, etc)Įnter fullscreen mode Exit fullscreen mode No ports need to be port forwarded or allowed through your firewallĬloudflare Tunnels use Cloudflared, a tunneling daemon to proxy the traffic from Cloudflare, and also to provide a CLI interface to make and manage tunnels.Linux server with a web server already configured on it.Domain added to Cloudflare (using CF nameservers, etc).Tunnels are free for any traffic amount with only a few limits: 1000 Tunnels per account, and 100 Active Connections from each tunnel to Cloudflare's edge. Now Cloudflare has completely separated the products, while you can still buy an Argo Subscription to try to speed up traffic to your origin. Cloudflare Argo is a service Cloudflare offers where they will use "smarter routing" to route requests to your origin avoiding network congestion, charging per gigabyte transferred. Cloudflare Tunnels used to be named Cloudflare Argo Tunnels, and required a Cloudflare Argo Subscription. You will need to grab the real user's IP from a header (normal cdn things) but also not rely on restricting any resources to localhost.Ĭloudflare Tunnels are completely free. It's important to remember that since the tunnel is acting as a proxy for traffic, the web server (or whatever you are exposing via the tunnel) will see all incoming traffic as localhost. This guide will focus on setting up a tunnel for a normal web server over http. Cloudflare Tunnels also use http/2 to connect to Cloudflare's Edge (soon http3/quic), whereas normally Cloudflare will only connect to an origin over http/1.1. The advantage of using Cloudflare Tunnels is not having to open any ports on your web server, no need for anything like IP Restrictions, Origin Cert checking, etc. Cloudflare Tunnels can be used to proxy normal http/https connections, ssh/vnc, as well as more advanced things like arbitrary TCP, with some more restrictions. Cloudflare Tunnels can be used to expose internal services using outbound only connections.
