Chapter 26 
Internet Access 
This chapter shows you how to configure the LAN and WAN of your Prestige for Internet access
.
 
26.1 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. 
26.2 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). 
26.3 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.
