Hi Francisco, The incoming Web requests listener only forwards requests to published Web servers. Only the Outgoing Web Requests listener allows proxying of client requests to the Internet.

If I am publishing Web Sites, I cant exclude the external listener in port 80 neither force authentication. Is this configuration secure or results in an open proxy ?
