The following figure illustrates a possible NAT application, where three inside LANs (logical LANs
using IP alias) behind the Device can communicate with three distinct WAN networks.

9.6.5 NAT Mapping Types
NAT supports five types of IP/port mapping. They are:
•
One to One
: In One-to-One mode, the Device maps one local IP address to one global IP
address.
•
Many to One
: In Many-to-One mode, the 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 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 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.
