PPPoE server configuration


Hello there
I have configure my exiting MikroTik router (which is in bridge mode as Woking as a Bandwidth controller as well) as a PPPoE server . Its an test network before I go to bigger implementation. I followed an online document from MikroTIK and able to configure it.
Currently i have two problems

  1. Customer who is not added in Secret Database can still connect to the network and access Internet. how can i prevent it.
  2. Customer who are behind NAT and installed Windows PPPoE dialer can not connect to the Network.
    I have attached an image of the network. And configuration of the PPPoE is given bellow. Looking forward for help

Regard
