You can achieve what you need with the "Mask" feature: If you set the
Mask of a pipe or queue to source or destination, a "virtual" pipe or
queue will be created for each source or destination IP matched by a
Thus, in your case, assuming you want each user host to have its own
128k pipe in each direction, you make two pipes, one for inbound
traffic with Mask set to Destination, and one for outbound with Mask
set to Source. For good measure you should also make two queues in the
same manner (for this, the "Weight" doesn't matter), althoug these
aren't strictly necessary.
You then need to make some rules, selecting inbound and outbound
traffic (on the WAN interface I assume) to your user hosts to go
through the apropriate queue (or pipe, if you didn't make queues),
incomming (on WAN) => queue/pipe with Mask=Destination, and outgoing
(on WAN) => queue/pipe with Mask=Source.
Hope this helps?
