6.7.3 PPPoE Encapsulation
The P-330W supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF Draft
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.

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). PPPoE provides a login and
authentication method that the existing Microsoft Dial-Up Networking software can activate,
and therefore requires no new learning or procedures for Windows users.

authentication method that the existing Microsoft Dial-Up Networking software can activate,
and therefore requires no new learning or procedures for Windows users.
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 P-330W (rather than individual computers), the
computers on the LAN do not need PPPoE software installed, since the P-330W does that part
of the task. Furthermore, with NAT, all of the LANs’ computers will have access.

Enable UPnP
UPnP (Universal Plug and Play) allows automatic discovery and configuration of
the Wireless Router. UPnP is by supported by Windows ME, XP, or later. Put a
check in this box to allow the router configuration to be changed by UPnP devices.
IPSec Passthrough Put a check in this box to enable computers on your LAN to make IPSec VPN
connections to servers on the Internet.
PPTP Passthrough Put a check in this box to enable computers on your LAN to make PPTP VPN
connections to servers on the Internet.
L2TP Passthrough Put a check in this box to enable computers on your LAN to make L2TP VPN
connections to servers on the Internet.
