5.6.2  PPPoE Encapsulation
The Prestige 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 Prestige (rather than individual computers), the 
computers on the LAN do not need PPPoE software installed, since the Prestige 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.
Spoof WAN MAC 
Address
The MAC address section allows users to configure the WAN port's MAC address 
by either using the factory default or cloning the MAC address from a computer on 
your LAN. 
Clear the check box to use the factory assigned default MAC Address.
Select this option and and click Clone MAC to clone the MAC address in the MAC 
Address field.
Clone MAC 
address
Enter the
 
MAC 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 
(ZyNOS configuration file). It will not change unless you change the setting or 
upload a different ROM file. 
Apply
Click Apply to save your changes back to the Prestige.
