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 ZyXEL device (rather than individual computers), the 
computers on the LAN do not need PPPoE software installed, since the ZyXEL device 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.
