    @Drax: Actually, you’re not correct there, that is dependent on the kernel version used, in fact, if you’re on a older kernel, such as 2.6.35 or thereabouts, you will definitely get this error as the netfilter (part of Linux’s iptables netfilter) in Kernel 3 has this feature that is not currently backported to the older kernels.
