2.8.3.3. Saving and Restoring IPTables Rules
Changes to
iptables
are transitory; if the system is rebooted or if the iptables
service is restarted, the rules are automatically flushed and reset. To save the rules so that they are loaded when the iptables
service is started, use the following command as the root user:
~]# service iptables save
iptables: Saving firewall rules to /etc/sysconfig/iptables:[ OK ]
The rules are stored in the file
/etc/sysconfig/iptables
and are applied whenever the service is started or the machine is rebooted.
