limit extension problem

[Michele Petrazzo - Unipex srl <michele.petrazzo@xxxxxxxxx>]

Hi all,
I'm on debian etch with the default kernel (iptables 1.3.6 and 2.6.18).

I'm trying the limit extension, but the invert flag doesn't work like
the man page say:
"""
iptables -t filter -A FORWARD -m mark --mark 2 -p icmp --icmp-type 8 -m
limit ! --limit 20/min -j ACCEPT
iptables v.1.3.6: limit does not support invert
"""
What I want it's to "limit" the log for icmp protocol to 20/minute

What can I do?

Thanks,
Michele
