6.1.2 NAT Configuration
This router supports the following types of NAT:
Many-To-One - In this case, multiple private IP addresses are mapped to one
Global IP address by using different ports.
Many-To-Many - In this case, multiple private IP addresses are mapped to a pool
of Global IP addresses.
One-To-One - In this case, one private IP address is mapped to one global IP
address. This type of NAT is used to enable internal servers (e.g. Web servers) to
be accessible from the Internet.
