It effectively works well, but I still have a problem:

When I use my bandwidth (download a huge file) and I start a ping at the
same time, latency grows from 15ms up to 300ms.
Again my conf:

hi,
when a pipe or queue has a mask of all 0's it only shows the addresses of
the first packet that matched, so you don't have to worry about that.
Also, if queues are linked to the pipe, the accounting is done on
the queues and not on the pipe.

cheers
