Re: my iptables setting not loaded after reboot in fc5

You should also change

IPTABLES_SAVE_ON_RESTART="no"

to

IPTABLES_SAVE_ON_RESTART="yes"

as well in /etc/sysconfig/iptables-config. Then make all the desired changes you
want in iptables rules and save them (just in case) by

iptables-save > /etc/sysconfig/iptables

Then your rules should survive system reboots.
