3.6. Saving Network Packet Filter Settings
3.6. Saving Network Packet Filter Settings After configuring the appropriate network packet filters for your situation, save the settings so they get restored after a reboot. For iptables , type the following command: /sbin/service iptables save This saves the settings in /etc/sysconfig/iptables so they can be recalled at boot time. Once this file is written, you are able to use the /sbin/service command to start, stop, and check the status (using the status switch) of iptables . The /sbin/service will automatically load the appropriate module for you. For an example of how to use the /sbin/service command, see Section 2.3, "Starting the Piranha Configuration Tool Service" . Finally, you need to be sure the appropriate service is set to activate on the proper runlevels. For more on this, see Section 2.1, "Configuring Services on the LVS Router" . The chapter explains how to use the Piranha Configuration Tool to configure the LVS router and describe the steps necessary to activate the Load Balancer Add-On.
