ZyWALL Series Internet Security Gateway
9.1.5 NAT Mapping Types
NAT supports five types of IP/port mapping. They are:
One to One: In One-to-One mode, the ZyWALL maps one local IP address to one global IP
address.
Many to One: In Many-to-One mode, the ZyWALL 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 ZyWALL maps the multiple
local IP addresses to shared global IP addresses.
Many One to One: In Many-One-to-One mode, the ZyWALL maps each local IP address to a
unique global IP address.
