18.2.5. Saving the Settings

Click OK to save the changes and enable or disable the firewall. If Enable firewall was selected, the options selected are translated to iptables commands and written to the /etc/sysconfig/iptables file. The iptables service is also started so that the firewall is activated immediately after saving the selected options. If Disable firewall was selected, the /etc/sysconfig/iptables file is removed and the iptables service is stopped immediately.

The selected options are also written to the /etc/sysconfig/system-config-selinux file so that the settings can be restored the next time the application is started. Do not edit this file by hand.

Even though the firewall is activated immediately, the iptables service is not configured to start automatically at boot time. Refer to Section 18.2.6, “Activating the IPTables Service” for more information.
