In this deployment environment, the PPPoA session is between the ADSL WAN 
interface and BRAS. The ADSL Router acts as a bridge and receives a public IP 
address from BRAS for your computer. And only the one that bears the public IP 
address is allowed to access the Internet. Moreover, no NAT translation will be done 
at this case.
