SUA Versus NAT
SUA (Single User Account) in previous ZyNOS versions is a NAT set with 2 rules, Many-to-One and
Server. The P-334WT now has Full Feature NAT support to map global IP addresses to local IP
addresses of clients or servers. With multiple global IP addresses, multiple severs of the same type (e.g.,
FTP servers) are allowed on the LAN for outside access. In previous ZyNOS versions (that supported
SUA 'visible' servers had to be of different types. The P-334WT supports NAT sets on a remote node
basis. They are reusable, but only one set is allowed for each remote node. The P-334WT supports 2 sets
since there is only one remote node. The default SUA (Read Only) Set in menu 15.1 is a convenient, pre-
configured, read only, Many-to-One mapping set, sufficient for most purposes and helpful to people
already familiar with SUA in previous ZyNOS versions.
