Prestige 660R ADSL 2+ Access Gateway
Chapter 17
Internet Access
.
This chapter shows you how to configure the LAN and WAN of your Prestige for Internet access
17.1 Internet Access Overview
Refer to the chapters on the web configurator's wizard, LAN and WAN screens for more background
information on fields in the SMT screens covered in this chapter.
17.2 IP Policies
Traditionally, routing is based on the destination address only and the router takes the shortest path to
forward a packet. IP Policy Routing (IPPR) provides a mechanism to override the default routing behavior
and alter the packet forwarding based on the policy defined by the network administrator. Policy-based
routing is applied to incoming packets on a per interface basis, prior to the normal routing. Create policies
using SMT menu 25 (see IP Policy Routing) and apply them on the Prestige LAN and/or WAN interfaces
using menus 3.2 (LAN) and 11.3 (WAN).
17.3 IP Alias
IP alias allows you to partition a physical network into different logical networks over the same Ethernet
interface. The Prestige supports three logical LAN interfaces via its single physical Ethernet interface with
the Prestige itself as the gateway for each LAN network.
Make sure that the subnets of the logical networks do not overlap.
The following figure shows a LAN divided into subnets A, B, and C.
