Loading additional iptables modules under CentOS 4.x

If you need a recurrent iptables modules to be loaded (let’s say the conntracking modules for FTP connections) you can either :

or

IPTABLES_MODULES="ip_conntrack_ftp"

Anytime you’ll start or restart iptables, the modules will be loaded :

<code>[root@localhost](1035)# service iptables condrestart
Flushing firewall rules:                                   [  OK  ]
Setting chains to policy ACCEPT: nat filter                [  OK  ]
Unloading iptables modules:                                [  OK  ]
Applying iptables firewall rules:                          [  OK  ]
Loading additional iptables modules: ip_conntrack_ftp      [  OK  ]</code>
