Speedtouch 510 QOS/bandwidth trottling

Hi,

Does anyone know some about trottling bandwidth with the Speedtouch 510.
I've configured it with DHCP spoofing, so the PC behind it will have the
Internet IP address (currently Windows Server). Windows doesn't provide the
QOS on the network that I require.

Does any know how to configure the Speedtouch or give some pointers to how
everything works together on the device?
Perhaps some supplemental documentation on how the inbound traffic responds
to the QOS of the speedtouch?

Tnx,
