10.2 Using NAT

10.2.1 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. 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. Select either SUA Only or Full Feature in the WAN IP screen.

10.3 SUA Server

A SUA server set is a list of inside (behind NAT on the LAN) servers, for example, web or
FTP, that you can make visible to the outside world even though SUA makes your whole
inside network appear as a single computer to the outside world.

through the ZyAIR.
