2.3.3 C o nne c tio n T ype : PPPo E
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, WiFi, 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 (rather than individual computers), the computers on the
LAN do not need PPPoE software installed, since the NBG does that part of the task. Furthermore, with
NAT, all of the LAN's computers will have Internet access.

DESC RIPT IO N
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 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.
