Chapter 3: Accessing the Internet
PPP over ATM (PPPoA) Mode
Description:
In this deployment environment, the PPPoA session is between the ADSL WAN
interface and BRAS. The IAD 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.
