The past days I have a similar problem with iprange .. I was able to see in the help the reference to iprange (like you are able to see the help related to FTOS) Well, the kernel *must* support FTOS. I suggest see in your kernel to know if FTOS is supported. This implies download the kernel source, then in the kernel source code directory. make menuconfig go to Network Options -> Netfilter configuration and search for that option in the kernel. Hope this help. Jorge.
