NAT Mapping Types
NAT supports five types of IP/port mapping. They are:
a. One-to-One: In One-to-One mode, the TC3162 EVM maps one local IP address to
one global IP address.
b. Many-to-One: In Many-to-One mode, the TC3162 EVM maps multiple local IP
addresses to one global IP address.
c. Many-to-Many Overload: In Many-to-Many Overload mode, the TC3162 EVM
maps multiple local IP addresses to shared global IP addresses.
d. Many-to-Many No Overload: In Many-to-Many No Overload mode, the TC3162
EVM maps each local IP address to a unique global IP address.
e. Server: This type allows you to specify inside servers of different services behind the
NAT to be accessible to the outside world.
The following table summarizes these types.
