This won't stop UDP though Have you considered putting two net cards in your linux machine and setting the machine up as a transparent ethernet bridge. You don't need to change any config on the client machines, but now you effectively have an invisible machine sitting inline that can block or prioritise traffic Ed W _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
