5.3.2 PPPoE Encapsulation

The LAN-Cell 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 PPPoE 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 LAN-Cell (rather than individual computers), the

computers on the LAN do not need PPPoE software installed, since the LAN-Cell does that

part of the task. Furthermore, with NAT, all of the LANs’ computers will have access.

The screen shown next is for PPPoE encapsulation.

Multicast Version Choose None (default), IGMP-V1 or IGMP-V2. IGMP (Internet Group Multicast

Protocol) is a session-layer protocol used to establish membership in a Multicast

group – it is not used to carry user data. IGMP version 2 (RFC 2236) is an

improvement over version 1 (RFC 1112) but IGMP version 1 is still in wide use. If

you would like to read more detailed information about interoperability between

IGMP version 2 and version 1, please see sections 4 and 5 of RFC 2236.

Spoof WAN MAC

Address from

LAN

You can configure the WAN port's MAC address by either using the factory

assigned default MAC Address or cloning the MAC address of a computer on your

LAN. By default, the LAN-Cell uses the factory assigned MAC Address to identify

itself on the WAN.

Otherwise, select the check box next to Spoof WAN MAC Address from LAN and

enter the IP address of the computer on the LAN whose MAC you are cloning.

Once it is successfully configured, the address will be copied to the rom file

(ProxiOS configuration file). It will not change unless you change the setting or

upload a different ROM file.

Clone the

computer’s MAC

address – IP

Address

Enter the IP address of the computer on the LAN whose MAC you are cloning.

If you clone the MAC address of a computer on your LAN, it is recommended that

you clone the MAC address prior to hooking up the WAN port.

Apply Click Apply to save your changes back to the LAN-Cell.
