unless you did one of these then they could access it from any ip address:
Code:
GRANT ALL PRIVILEGES ON *.* TO 'user'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;
But yes you are both correct, my point was that it is not needed for a regular home brew server, only for special cases like Angelox's. So basically if you are not sure that you need it then you probably don't. As for the other ports try turning off all of the tcp ports and just leave the udps I bet you will have no issues. Just a more secure firewall. You may need to leave tcp on port 9000 if you use the telnet feature, I usually only use this through vpn if I need to though, since telnet by default is unsecure.
