4.3SUA (Single User Account) Versus NAT

SUA (Single User Account) in previous ZyNOS versions is a NAT set with 2 rules, Many-to-One and Server. See section 4.5.1 for a detailed description of the NAT set for SUA. The Prestige now has Full Feature NAT support to map global IP addresses to local IP addresses of clients or servers using all mapping types as outlined in Table 4-1 NAT Mapping Types. The Prestige supports NAT sets on a remote node basis. They are reusable, but only one set is allowed for each remote node. The last set (SUA Only option in Menu 15.1) is a convenient, pre-configured, read only Many-to-1 port mapping set, sufficient for most purposes (see section

4.6for some examples) and helpful to people already familiar with SUA in previous ZyNOS versions.

Please upload the latest configuration file (romfile) for NAT and SUA to work properly.
