• 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-202H Plus v2 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-202H
Plus v2 supports NAT sets on a remote node basis. They are reusable, but only
one set is allowed for each remote node. The P-202H Plus v2 312 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.
