Still can't able to load modules using /etc/sysconfig/iptables-config

all modules are present (ip_nat_ftp,ip_conntrack_ftp)

slocate cache database being updated (using updatedb)

# Load additional iptables modules (nat helpers)
#   Default: -none-
# Space separated list of nat helpers (e.g. 'ip_nat_ftp ip_nat_irc'), which
# are loaded after the firewall rules are applied. Options for the helpers are
