While you need to identify traffic somehow in order to apply QoS, I don't see why you have to identify traffic by port alone. Set up different priorities for other hosts versus this FTP server's IP; or match other traffic types first and leave the generic "high ports" to "high ports" for the lowest priority. [ I'm still at the tinkering stage of using bandwidth shaping myself, but bandwidth limits are appropriate when you pay by the byte or have usage limits in place. QoS is better (more useful?) when you've got unlimited connectivity, or busy pipes, or both. ] -Chuck To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
