16.2 Using NAT

You must create a firewall rule in addition to setting up SUA/NAT, to allow
traffic from the WAN to be forwarded through the ZyWALL.

16.2.1 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 ZyWALL also supports Full Feature NAT
to map multiple global IP addresses to multiple private LAN IP addresses of clients or servers
using mapping types. Select either SUA or Full Feature in NAT Overview.
Selecting SUA means (latent) multiple WAN-to-LAN address translation.
