Internet Access
This chapter shows you how to configure your Prestige for Internet Access
.
7.1 Internet Access Overview
This section provides information on configuring your Prestige for Internet access. It includes information
on encapsulation types, IP address assignment and ATM networks.
7.2 Encapsulation
Be sure to use the encapsulation method required by your ISP. The Prestige supports the following
methods.
7.2.1 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
Ethernet
Encapsulation Gateway field in menu 4 and in the Rem IP Addr field in menu 11.1. You can get this
information from your ISP.
7.2.2 PPP over Ethernet
PPPoE provides access control and billing functionality in a manner similar to dial-up services using PPP.
The Prestige bridges a PPP session over Ethernet (PPP over Ethernet, RFC 2516) from your computer to an
ATM PVC (Permanent Virtual Circuit), which connects to a DSL Access Concentrator where the PPP
session terminates. One PVC can support any number of PPP sessions from your LAN. For more
information on PPPoE, see the Appendices.
