Activating the iptables Service

The firewall rules will only be active if the iptables service is running. To manual start the service, use the command:

/sbin/service iptables restart

To ensure that it is started when the system is booted, issue the command:

/sbin/chkconfig --level 345 iptables on

You can also use Serviceconf to activate iptables. See the Section called Services Configuration Tool in Chapter 13.

You can not run the ipchains service along with the iptables service. To make sure the ipchains service is disabled, execute the command:

/sbin/chkconfig --level 345 ipchains off
