Description:
In this deployment environment, the PPPoE session is between the ADSL WAN interface and BRAS. The ADSL
Router gets a public IP address from BRAS when connecting to DSLAM. The multiple client PCs will get private IP
address from the DHCP server enabled on private LAN. The enabled NAT mechanism will translate the IP
information for clients to access the Internet.
