•
One to One
: In One-to-One mode, the ZyXEL Device maps one local IP address to one
global IP address.
•
Many to One
: In Many-to-One mode, the ZyXEL Device maps multiple local IP
addresses to one global IP address. This is equivalent to SUA (for instance, PAT, port
address translation), ZyXEL’s Single User Account feature that previous ZyXEL routers
supported (the
SUA Only
option in today’s routers).
•
Many to Many Overload
: In Many-to-Many Overload mode, the ZyXEL Device maps
the multiple local IP addresses to shared global IP addresses.
•
Many-to-Many No Overload
: In Many-to-Many No Overload mode, the ZyXEL Device
maps each local IP address to a unique global IP address.
•
Server
: This type allows you to specify inside servers of different services behind the
NAT to be accessible to the outside world.
Port numbers do NOT change for
One-to-One
and
Many-to-Many No Overload
NAT
mapping types.
The following table summarizes these types.
8.3.6 SUA (Single User Account) Versus NAT

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.
