ZyAIR G-2000 Plus User's Guide
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 ZyAIR (rather than individual computers), the
computers on the LAN do not need PPPoE software installed, since the ZyAIR 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.
