Recent Match Problem

on 64 bit linux the error is like this:

iptables: Unknown error 18446744073709551615

You should increase maximum possible value for –hitcount parameter (20 by default) by setting ipt_recent module option ip_pkt_list_tot.

For example:

# cat /etc/modprobe.d/ipt.conf 
options ipt_recent ip_pkt_list_tot=200

Then reload module ipt_recent.
