The doorman is intended to run on systems which have their firewall rules turned down tightly enough as to be effectively invisible to the outside world.The doorman adds and removes extra rules in a carefully controlled manner.
Using metaphor 1...
The doorman daemon "guards the door" of a host, admitting only recognized parties. It allows a server which is not intended for general public access to run with all of its TCP ports closed to the outside world. A matching "knocker" is provided, with which to persuade the doorman to open the door a crack, just wide enough for a single TCP connection from a single IP address.
