6.3 Technical Reference
The following section contains additional technical information about the Zyxel Device features
described in this chapter.
Encapsulation
Be sure to use the encapsulation method required by your ISP. The Zyxel Device can work in bridge
mode or routing mode. When the Zyxel Device is in routing mode, it supports the following methods.
IP over Ethernet
IP over Ethernet (IPoE) is an alternative to PPPoE. IP packets are being delivered across an Ethernet
network, without using PPP encapsulation. They 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 Ethernet cells.
PPP over Ethernet (PPPoE)
Point-to-Point Protocol over Ethernet (PPPoE) provides access control and billing functionality in a
manner similar to dial-up services using PPP. PPPoE is an IETF standard (RFC 2516) specifying how a
personal computer (PC) interacts with a broadband modem (DSL, cable, wireless, and so on)
connection.
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.
