Or actually the preferred interface for this type of operations is to use iptables-restore, the batch version of iptables. The speed difference from using iptables-restore and direct calls is pretty minimal by any means. libiptc is an internal interface of the iptables source tree and is subject to change at any time. This should not be used directly unless you have very good reasons. Regards Henrik
