Umar,

if you want to limit per IP address, you need to create one queue for
every IP address in your internal network. The bandwidth sum of all
queues must not exceed the bandwidth of the root queue. If your
upstream has a b/w of 256 kBit/s (if it's asymmetric) you can only
create 25 queues with 10 kBit/s.

You may consider doing it different, as creating one queue for every
internal IP address is a nightmare for administration.

I'm using hfsc scheduler for the internal network, so every IP should
be served fair and a limited cbq queue for them on the external
interface and reach good results with that. If b/w is limited as other
traffic passes, these stations get their traffic through limited.
