ISPConfig firewall problem closing Port 21
I'm running a webserver with Suse 10.2 configured with ispconfig.
Also I'm using the ispconfig firewall, but can't configure that well for port 21.
I do run proftpd but I run this on a different port, when I try to close port 21 in ispconfig it keeps open although proftpd is running on another port?
The bastille-firewall.cfg shows under TCP_PUBLIC_SERVICES the non-default ftp port, other running services and ftp pasv mode ports.
Port 21 isn't in there but I'm not able to get it closed, could anyone help me out?
