Traffic can be assigned to queue not necessarily on the interface/direction the traffic takes effect on. Eg, you have queue ftp_out, that is designed to let your desktop to upload to some sites no faster than some speed, and of course the queue being defined on $ext_if. But the rule assigning traffic to it would be something like "pass in on $int_if from $my_desktop to any proto tcp port ftp queue ftp_out" I hope that makes sense. > Thanks. > > Chris -- viq ---------------------------------------------------------------------- Jestem niesamowita... ;-) >>> http://link.interia.pl/f18b8
