10.1.5 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 (i.e., PAT, port address translation), ZyXEL’s Single User
Account feature (the SUA Only option).

Many-to-Many Overload: In Many-to-Many Overload mode, the Prestige maps the multiple local

IP addresses to shared global IP addresses.
