Network Address Translation
This chapter discusses how to configure NAT on the Prestige.

28.1 Using NAT

Note: 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-One and Server. See
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.
Note: 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.
