4.2 Using NAT
4.2.1 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. See section 4.3.1 for a detailed 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 as outlined in Table 4-2.
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.
