Network Address Translation 
(NAT)
This chapter discusses how to configure NAT on the Prestige.
29.1  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.
29.1.1  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 
 or 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.
• Choose SUA Only if you have just one public WAN IP address for your Prestige.
• Choose Full Feature if you have multiple public WAN IP addresses for your Prestige.
29.2  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
