Hi, I think you could mark packets based on ports 1863 and hosts messenger.hotmail.com , gateway.messenger.hotmail.com, webmessenger.msn.com On 7/5/07, Randy D. Wallace Jr. <randywallacejr@xxxxxxxxx> wrote:

Have you checked to make sure that the layer7 module is catching msnmessenger traffic? It would be a good idea to try #iptables -A PREROUTING -i eth1 -p tcp -m layer7 --l7proto msnmessenger -j LOG \ - --log-prefix 'MSN Messenger Packet: ' and consult /var/log/messages and make sure that layer7 is seeing it. If it's not, the packets for msn traffic will never get marked. a much better solution would be to mark based on destination port, and let connection tracking take care of the rest. for example: #DNS Traffic #iptables -A FORWARD -i eth1 -p tcp --dport 53 -j MARK --set-mark 2 #iptables -A FORWARD -p tcp -m state --state RELATED,ESTABLISHED -j ACCEPT #iptables -A FORWARD -p udp -m state --state NEW,RELATED,ESTABLISHED -j ACCEPT hope this helps! > > I add the rules from DNS and FTP too . > > But it's not seems to work . > > Any help will be appreciated . > > Saulo Silva -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFGjNtxE5g7hmMpaLoRAuFwAJ9ePBgmBCQfToFaT24PZFvdIhH20ACgq52E pFsHeJgpBIGDG6oPHdhZpnc= =TgHZ -----END PGP SIGNATURE----- _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
