Finetuning Bastille firewall
I would like to restrict ssh access to a few IP address ranges. Is this possible without shutting the ISPConfig/Bastille firewall (off and using your complete own iptables rules))? e.g. is there a Bastille config file where I could add additional iptables directives so that these get added to the ones done by ISPConfig and not overwritten if changes are made in ISPConfig?
