6.4 WAN Technical Reference
This section provides some technical background information about the topics covered in this chapter.
6.4.1 Encapsulation
Be sure to use the encapsulation method required by your ISP. The ZyXEL Device supports the following methods.
6.4.1.1 ENET ENCAP
The MAC Encapsulated Routing Link Protocol (ENET ENCAP) is only implemented with the IP network protocol. IP packets are routed between the Ethernet interface and the WAN interface and then formatted so that they can be understood in a bridged environment. For instance, it encapsulates routed Ethernet frames into bridged ATM cells. ENET ENCAP requires that you specify a gateway IP address in the Gateway IP Address field in the wizard or WAN screen. You can get this information from your ISP.
6.4.1.2 PPP over Ethernet
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,
