I delayed posting this because I'm not sure this answer is correct. I think you need to have both in and out traffic handled or your priority won't work, because outgoing traffic will be at higher prioriy, but incomming will be relegated to the lower priority, thus your overall priority won't be improved any. Maybe something like: ipfw pipe 1 config bw 64Kbit/s ipfw queue 1 config pipe 1 weight 90 ipfw queue 2 config pipe 1 weight 1 ipfw add 400 queue 1 tcp from 192.168.0.50 to any ipfw add 450 queue 1 tcp from any to 192.168.0.50 ipfw add 500 queue 2 ip from any to any See if that helps. And again, I'm not sure I have the right answer for you, so take it with a grain of salt. Also, make sure the traffic you're trying to prioritize is travelling on tcp, if not, it will be running at the lower priority. -- Bill Moran Potential Technologies http://www.potentialtech.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
