iptables creating rules after restarting the iptables. When iptables service is restarted settings from /etc/sysconfig/iptables file are applied and used with the iptables.

You can either set up iptables rule so that current stat is saved the rule upon restart or stop/start:

You need to make changes in following file as per your requirement for values received in following GREP result.

root@server[~]# grep IPTABLES_SAVE /etc/sysconfig/iptables-config
IPTABLES_SAVE_ON_STOP=”no”
IPTABLES_SAVE_ON_RESTART=”no”
IPTABLES_SAVE_COUNTER=”no”

Or overwrite current settings with iptables-save to /etc/sysconfig/iptables file:

root@server[~]# iptables-save > /etc/sysconfig/iptables

Note : Its always good if we use NO option for following options because some time due to wrong rule we face major problem to access server.

IPTABLES_SAVE_ON_STOP=”no”
IPTABLES_SAVE_ON_RESTART=”no”
IPTABLES_SAVE_COUNTER=”no”
