Furthermore, note that with -M '', you will want to modprobe ip_tables or modprobe ip6_tables manually first at system startup (or build them into the kernel), since those modules don't autoload (hence why iptables tries to load them). I wonder if there's an easy way iptables userspace could detect whether these modules are already loaded (or compiled into the kernel), and not even try to load them, if so... - Maciej
