+tunneling daemon that proxies traffic from the Cloudflare network to your
+origins.  This daemon sits between Cloudflare network and your origin (e.g. a
+webserver).  Cloudflare attracts client requests and sends them to you via
+this daemon, without requiring you to poke holes on your firewall --- your
+origin can remain as closed as possible.")
