48.8.3.3. 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:
service iptables save
The rules are stored in the file
/etc/sysconfig/iptables and are applied whenever the service is started or the machine is rebooted.
