Bandwidth limitation on CRS 317 in Bridge mode.

Hi,
I struggle with getting Simple Queue to work with my CRS317 in Bridge Mode.
Is it possible to get this to work in bridge mode ?
My scenario is as follows. I have one internet provider, and a 100Mbit I need to distribute to 5-10 customers.
I would like to have the possibility to limit each customer to the BW they pay for.

Have done the setup earlier with a CCR in Router Mode, ( was given an own subnet then) worked fine. Now my CRS and Customers are
sharing the same subnet as the CPE from my provider. See network picture.
