Chapter 10 WAN 10.4.2 PPPoE Encapsulation The ARMOR Z1 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 ARMOR Z1 (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the ARMOR Z1 does that part of the task. Furthermore, with NAT, all of the LANs' computers will have access. ARMOR Z1 User's Guide 74

PPPoE Encapsulation
The ARMOR Z1 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 ARMOR Z1 (rather than individual computers), the
computers on the LAN do not need PPPoE software installed, since the ARMOR Z1 does that part of
the task. Furthermore, with NAT, all of the LANs’ computers will have access.
