11.2 SUA (Single User Account) Versus NAT
SUA (Single User Account) is a ZyXEL implementation of a subset of NAT that supports two types of
mapping, Many-to-One and Server. See section 11.3.1 for a detailed description of the NAT set for
SUA. The Prestige supports Full Feature NAT to map multiple global IP addresses to multiple private
LAN IP addresses of clients or servers using mapping types as outlined in Table 11-2.
1. Choose SUA Only if you have just one public WAN IP address for your
Prestige.
2. Choose Full Feature if you have multiple public WAN IP addresses for your
Prestige.
