I have enabled and disabled. Âeg. If I explicitly enable the
webserver, it should open the corresponding port(s).
Actually, just be a service is running doesn't mean you want it exposed to the world. I work as a web developer, so I have httpd running on my system, but this doesn't me that I want everyone to be able to access this. My httpd session is just for personal development and doesn't need to be exposed just because it's running.
