7 .3 .2   PPPo E Enc a p sula tio n

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 o ve r Ethe rne t 

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).
