Security setting to prevent passive ftp?

[Jonathan August]

The modprobe ip_conntrack_ftp doesn't return anything and it seems to  
still have an issue...  Do I need to reboot or something?

Also, what do I add to /etc/sysconfig/iptables-config?  There just  
seems to be a few things in there with YES or NO settings...

??

Thanks,
-Jon
