There  are three iptables modules that need to be loaded by hand or called in a script to work in an iptables firewall:

ip_tables
ip_conntrack_ftp
ip_nat_ftp

Since ip_tables is the core module (and pulls in most of the others), you will not have a functioning iptables firewall without this one loaded.
