NBG-418N v2 User’s Guide

The NBG-418N v2 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.
