How to NAT a PPPoE dynamic interface to connect to public internet

[M.Fly]

Hi all,

we have a ISP infrastructure, where che customer is authenticated via PPPoE on a leased line, for example, a VDSL line.
The customer have a PPPoE with a private IP address on the PPPoE Client.
The virtual-template have a loopback with a Public IP Address, this ip address is the next-hop for a PPPoE tunnel.

We want to NAT the private IP address on a PPPoE client to the public IP address of a Loopback or public interface of BNG router.

We try with ip nat inside on loopback1 and ip nat outside on the public interface of BNG with a access-list that match only the private IP address of the PPPoE Client, but nothing appened.

Can suggest any solution?
Many thanks.
