9.1.5SUA (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-Oneand 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.
