Chapter 6 Broadband
6.2.1 Add/Edit Broadband
Click Add new WAN interface in the Broadband screen or the Edit icon next to an existing WAN interface to configure a WAN connection. The screen differs according to the mode and encapsulation you choose.
6.2.2 PPPoE Encapsulation
The ZyXEL Device supports 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 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.
