IPTables won't start

If you use the iptables service you must define your rules defined in 
/etc/sysconfig/iptables. You can edit some defaults in 
/etc/sysconfig/iptables-config.

Otherwise you can make an shell-script which loads the rules. Quick example:
=================
#!/bin/sh

echo

echo "Loading some modules"
/sbin/modprobe ip_conntrack
/sbin/modprobe ip_nat_ftp
/sbin/modprobe ip_conntrack_ftp

echo

echo "Deleting all existing rules"
iptables -F
iptables -t nat -F

echo

echo "chain defaults"
iptables -P INPUT ACCEPT
iptables -P OUTPUT ACCEPT
iptables -P FORWARD ACCEPT

# HTTP
iptables -A INPUT -p 6 -s 0/0 -d 1.2.3.4--dport  80 -j ACCEPT
iptables -A INPUT -p 6 -s 0/0 -d 1.2.3.4--dport 443 -j ACCEPT

=================

You can just execute this script to load the firewall... check with 
"iptables -L".

Goodluck,
