Chapter 16
Network Address Translation (NAT)
This chapter discusses how to configure NAT on the Prestige.
16.1 NAT Overview
16.1.1 SUA (Single User Account) Versus NAT
SUA (Single User Account) is a ZyNOS implementation of a subset of NAT that supports two types of
mapping, Many-to-One and Server. See section 16.3.1 for a detailed description of the NAT set for SUA.
The Prestige also supports Full Feature NAT to map multiple global IP addresses to multiple private LAN
IP addresses of clients or servers using mapping types as outlined in the web configurator part of this guide.
1. Choose SUA Only if you have just one public WAN IP address for your Prestige.
2. Choose Full Feature if you have multiple public WAN IP addresses for your Prestige.
16.2 Applying NAT
You apply NAT via menus 4 or 11.3 as displayed next. The next figure shows you how to apply NAT for
Internet access in menu 4. Enter 4 from the main menu to go to Menu 4 - Internet Access Setup.
