If guess if you are thinking that the order of starting up could be the
cause of it, the it might be easier if you do a simple hack as follows -
its not the safest way, but heck, I'm hoping it will work for you :)
# iptables -F
# iptables -Z
# service iptables save
# chkconfig iptables on
Put all your iptables rules into a script file
# vi /root/myfirewall.sh
$IPTABLES -A INPUT -s 192.168.1.1 -j ACCEPT
<or whatever needs to be done>
<save and exit>
# chmod 700 /root/myfirewall.sh
Add the script file into rc.local
# echo "/root/myfirewall.sh" >> /etc/rc.d/rc.local
Every time upon reboot, the rc.local file gets called right at the last
and in that sequence your /root/myfirewall.sh gets called just before
the system is ready to accept logins. All other services should have
been up and running long before the /root/myfirewall.sh gets called.
