NAT

 

 

31-1 

Chapter 31

 

Network Address Translation (NAT) 

This chapter discusses how to configure NAT on the Prestige. 

31.1 Using NAT 

You must create a firewall rule in addition to setting up SUA/NAT, to allow traffic 

from the WAN to be forwarded through the Prestige. 

31.1.1 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 31.3.1

 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 User’s 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. 

31.2 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

.
