8.3.2
PPPoE Encapsulation
The NBG-416N 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).
One of the benefits of PPPoE is the ability to let you 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 individuals.
Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as
it requires no specific configuration of the broadband modem at the customer site.
By implementing PPPoE directly on the NBG-416N (rather than individual
computers), the computers on the LAN do not need PPPoE software installed,
since the NBG-416N does that part of the task. Furthermore, with NAT, all of the
LANs’ computers will have access.
This screen displays when you select
PPPoE
encapsulation.

PPTP Encapsulation
Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables secure
transfer of data from a remote client to a private server, creating a Virtual Private
Network (VPN) using TCP/IP-based networks.

ISP Parameters for Internet Access
Connection Type
Point-to-Point Tunneling Protocol (PPTP) is a network protocol that
enables secure transfer of data from a remote client to a private
server, creating a Virtual Private Network (VPN) using TCP/IP-based
networks. PPTP supports on-demand, multi-protocol, and virtual
private networking over public networks, such as the Internet. The
NBG-416N supports only one PPTP server connection at any given
time.
To configure a PPTP client, you must configure the
User Name

Password
fields for a PPP connection and the PPTP parameters for
a PPTP connection.
User Name
Type the user name given to you by your ISP.
