Chapter 8 WAN

User’s Guide

The NBG4115 supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an 
IETF standard (RFC 2516) specifying how a personal computer (PC) interacts with 
a broadband modem (DSL, cable, wireless, etc.) connection. The PPP over 
Ethernet option is for a dial-up connection using PPPoE.

For the service provider, PPPoE offers an access and authentication method that 
works with existing access control systems (for example Radius).
