PCQ with PPPoE and NAT

I have a RB750 at home. It’s port 1 is connected to the ISP network and the address is assigned dynamically from 10.10.10.0/24
That’s a town network for file sharing,chatting and the like.
However,my WAN connection type is PPPoE. My home network is 192.168.0.0/24.
How do I configure PCQ for WAN traffic,so that the wan connection bandwidth is equally shared among my home users?
I want to shape only my WAN connection bandwidth without affecting my town lan connection bandwidth.
