Hi, Alberto.  I'm afraid I don't have time to look up the details but I
think you will be able to do what you want to do with iproute2 and
packet marking.  The details will be in a file named ip-cref.ps in the
rules section.  On my RedHat 9.0 distribution it is
/usr/share/doc/iproute-2.4.7/ip-cref.ps.  You can also find a brief
slide show on using it with iptables and *swan in the training section
of the ISCS network security management web page at
http://iscs.sourceforge.net

Good luck - John
