iptables -m nth doesn't work!

[qmx]

# iptables -t mangle -A PREROUTING -i lo -m nth --every 2 -j MARK --set-mark 1
iptables: No chain/target/match by that name


any ideas?

ps: patch-o-matic already applyed on kernel + iptables HAS libipt_nth.so

Is it compiled as a module or into the kernel? Show us your lsmod and kernel version.

is compiled inside kernel. iptables has .so file too, but when i try to apply a rule it says: invalid chain/match/target

I noticed that with my setup I had to use the -p tcp or -p udp option before I state my -m arguments.
