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 |
The ipchains service can not be run along with the iptables service. To make sure the ipchains service is disabled, execute the command:
/sbin/chkconfig --level 345 ipchains off |
The Services Configuration Tool can be used to configure the iptables and ipchains services. See Section 14.3 Services Configuration Tool for details.
