How do I create rules to allow FTP passive and active connections to the server ?Do I use ip_conntrack_ftp or can I just create some rules that will do the job ?You need ip_conntrack_ftp. To get that modules loaded automatically, Just edit /etc/sysconfig/iptables and add "ip_conntrack_ftp" to the "IPTABLES_MODULES=" line.
Okay I have ip_conntrack_ftp loaded in /etc/sysconfig/iptables-config. Still it must require some rules to use it. Aaron
