Prestige 334W User’s Guide

Chapter 28

Network Address Translation (NAT)

This chapter discusses how to configure NAT on the Prestige.

28.1 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.

28.1.1 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-Oneand Server. See section 28.3.1 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.

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.

28.2 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.
