The following table summarizes these types.
7.2 Using NAT
7.2.1 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 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. Select either
SUA Only
or
Full Feature
in the
WAN IP
screen.
7.3 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.

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.
