log-messages of iptables

[Frank Geschner <fgeschner@gmx.net>]

i've got a minimal installation of debian3.0r2 with iptables and ipmasq.
however, after installing ipmasq i get lot of messages onto my console 
in the following manner:

IN=eth0 out= MAC:#=01:00 .... PROTO=2

i thought that the entry at /etc/syslog.conf

kern.*    -/var/log/kern.log

means that messages of this kind are logged there. but they were wrote 
into this file and additionally to the console and that is nerved.

how can i avoid this effect?

thanks in advance.
