I would like to close any connection on Port 80 if there is no request to a existing TLD as example if there are direct requests to the server IP that is not assign to a specific webpage. For this i changed the default nginx port from 80 to something else. Sadly that did work for only a few seconds because suddendly i got the standard ISPConfig index page (and don't know where it came from). What can i do to prevent this happening and how can i close port 80 if there is no Webpage for this IP Adress.
