ZyWALL 10~100 Series Internet Security Gateway
9-4 Internet Access
9.1.4 PPPoE Encapsulation
The ZyWALL 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 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). 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.
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 ZyWALL (rather than individual computers), the computers on the
LAN do not need PPPoE software installed, since the ZyWALL does that part of the task. Furthermore, with
NAT, all of the LANs’ computers will have access.
If you enable PPPoE in menu 4, you will see the next screen. For more information on PPPoE, please see the
Appendices.
