9.1.5 SUA (Single User Account) Versus NAT
SUA (Single User Account) in previous ZyNOS versions is a subset of NAT that supports two types of mapping,
Many-to-One and Server. See section 9.2.3 for a detailed description of the NAT set for SUA. The Prestige has
Full Feature NAT support to map local IP addresses to global IP addresses of clients or servers using all mapping
types as outlined in Table 9-1. The Prestige supports NAT sets on a remote node basis. The mapping sets are
reusable, but only one set is allowed for each remote node. Set 255 is for SUA Only which is a convenient, pre-
configured, read only Many-to-1 port mapping set, sufficient for users with just one public IP.
