Welcome to Argo Tunnel. If you have any ideas, run into any odd behaviors or want to share what you build with Argo Tunnel, the dev team is following the feedback forum here.
Argo Tunnel offers an easy way to expose web servers securely to the internet, without opening up firewall ports and configuring ACLs. Tunnel also ensures requests route through Cloudflare before reaching the web server, so you can be sure attack traffic is stopped with Cloudflare’s WAF and Unmetered DDoS mitigation and authenticated with Access. To use Tunnel, you install and run a daemon on the web server that creates a persistent connection out to Cloudflare. Because the web server is otherwise locked down to external requests, only connection from Cloudflare over that persistent connection can make it back to the server.
Argo Tunnel is free with the purchase of Argo Smart Routing. Argo Smart Routing can be purchased in the Cloudflare dashboard and costs $5/month plus 10 cents per GB.
