You might need a kernel module. Try this command to see which modules are available: find /lib/modules/|grep conntrack This command to see which modules are currently loaded in your kernel: lsmod See also rmmon and insmod. But I would have thought they'd be automatically installed by the iptables command. IDK more about iptables sorry... good luck,
