By default, WebServer accepts requests from all IP addresses. In paranoid mode, the server only accepts requests from specified IP addresses. It provides two methods, acceptClient( ) and denyClient( ), for building lists of approved and rejected clients. By default, no client connections are accepted when setParanoid( ) has been called with an argument of true. You'll need to use the acceptClient( ) method to add approved IP addresses, and can use denyClient( ) to trim that list. Once an IP address has been put on the denied list, acceptClient( ) can't bring it back -- denials are more permanent than acceptances.
