I'm very new to firewall and am sure I'm just doing it wrong. My problem is that I want a specific port closed but removing it from the list of open ports in ispconfig doesn't close it. Maybe that's not the way to do it, if so, please tell me. Basically I have a mysql database set up on a different port than 3306 and I don't want it public, however even if the port is not listed as open in the rules on ispconfig, it's still accessible from outside the local network. If possible I'd like to open that specific port only to a specific ipadress if possible. Can I create specific rules at all or is it just "open" or nothing? Sorry if this is a newb question and if it's already been answered before, I tried my best to find answers in the forum.
