Description:
In this deployment environment, the PPPoE session is between the ADSL WAN
interface and BRAS. The ADSL Router acts as a bridge and gets a public IP address
from BRAS for your computer. And only the one that got the public IP address is
allowed to access into Internet. The real IP that you got is acquired from ISP.
Moreover, no NAT translation will be done at this case.
