Chapter 6 Network Address Translation (NAT) Screens
6.1.5 NAT Mapping Types
NAT supports five types of IP/port mapping. They are:
•
One to One
: In One-to-One mode, the Prestige maps one local IP address to one global
IP address.
•
Many to One
: In Many-to-One mode, the Prestige 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 Prestige maps the
multiple local IP addresses to shared global IP addresses.
•
Many-to-Many No Overload
: In Many-to-Many No Overload mode, the Prestige 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.
