Hi! I'm using pipe masks for defining multiple queues per traffic flow, e.g. $cmd pipe 100 config mask all bw $webclient_upload_bandwidth queue $queue_size delay $client_rtt_delay $cmd pipe 200 config mask all bw $webclient_download_bandwidth queue $queue_size delay $client_rtt_delay $cmd add pipe 100 all from $client1_subnet to $server1_subnet in recv $in_if $cmd add pipe 200 all from $server1_subnet to $client1_subnet out xmit $in_if As you can see in the example above I'm defining a fixed delay value for all queues. Is it possible to define a delay distribution, e.g. min. 20ms, mean 50ms and max. 80ms for the pipe? I had a look at the ipfw howto (http://www.freebsd-howto.com/HOWTO/Ipfw-HOWTO), but couldn't find anything there nor via google. Thanks in advance for any help! Regards, Sebastian
