2.3.3 Connection Type: PPPoE

Point-to-Point Protocol over Ethernet (PPPoE) functions as a dial-up connection. PPPoE is an IETF
(Internet Engineering Task Force) standard specifying how a host personal computer interacts with
a broadband modem (for example DSL, cable, wireless, etc.) to achieve access to high-speed data
networks.
For the service provider, PPPoE offers an access and authentication method that works with existing
access control systems (for instance, RADIUS).
One of the benefits of PPPoE is the ability to let end users access one of multiple network services,
a function known as dynamic service selection. This enables the service provider to easily create
and offer new IP services for specific users.
Operationally, PPPoE saves significant effort for both the subscriber and the ISP/carrier, as it
requires no specific configuration of the broadband modem at the subscriber's site.
By implementing PPPoE directly on the NBG-419N (rather than individual computers), the
computers on the LAN do not need PPPoE software installed, since the NBG-419N does that part of
the task. Furthermore, with NAT, all of the LAN's computers will have Internet access.

DESCRIPTION
Enter the gateway IP address in this field.
DNS (Domain Name System) is for mapping a domain name to its
corresponding IP address and vice versa. The DNS server is extremely
important because without it, you must know the IP address of a
computer before you can access it. The NBG-419N uses a system DNS
server (in the order you specify here) to resolve domain names for DDNS
and the time server.
Enter the primary DNS server's IP address in the fields provided.
Enter the secondary DNS server's IP address in the fields provided.
