10.2 SUA (Single User Account) Versus NAT

SUA (Single User Account) is a ZyNOS implementation of a subset of NAT that supports two
types of mapping, Many-to-One and Server. The ZyXEL Device also supports Full
Feature NAT to map multiple global IP addresses to multiple private LAN IP addresses of
clients or servers using mapping types as outlined in
• Choose SUA Only if you have just one public WAN IP address for your ZyXEL Device.
• Choose Full Feature if you have multiple public WAN IP addresses for your ZyXEL
Device.

You must create a firewall rule in addition to setting up SUA/NAT, to allow traffic from the
