Bastille - Open port to one IP (mysql)??
I need to configure a mysql replication where ISPconfig will be the master. Until now the mysql port (3306) was closed.
I'm concerned by the security and I don't want this port opened for all but only one ip (mysql slave). How can I do this?
At the GUI interface we only can configure ports, not IP.
We must configure custom iptables rules?
I know that if I leave the mysql port opened I can control the access to mysql with mysql authentication (user/localhost), but it's more secure if the firewall block it, no??
