PPP over ATm (PPPoA) IP Extension mode

Description: 

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.
