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

28.1 Using NAT

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 section Address Mapping Sets for a
detailed description of the NAT set for SUA. The ZyAIR also supports Full Feature NAT to
map multiple global IP addresses to multiple private LAN IP addresses of clients or servers
using mapping types.

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.
