The problem is that may be you cannot know in advance the ports or ip numbers of your connections, in that case I don't know what could help you. t t -- vincent-perrier <vincent-perrier@xxxxxxxxxxxxxxxx> _______________________________________________ LARTC mailing list / LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
