9.1.5 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. Select either SUA
Only or Full Feature in WAN IP.
Selecting SUA Only means (latent) multiple WAN-to-LAN and WAN-to-DMZ multiple address translation.
That means that computers on your DMZ with public IP addresses will still have to undergo NAT mapping if
you're using SUA Only NAT mapping. If this is not your intention, then select Full Feature NAT and don't
configure NAT mapping rules to those computers with public IP addresses on the DMZ.

Configuring NAT

You must create a firewall rule in addition to setting up NAT, to allow traffic from the WAN to be forwarded
through the ZyXEL device.
Select a device and then click Configuration > NAT.
