Setup Tab - One-to-One NAT

One-to-One NAT creates a relationship which maps valid external addresses to internal addresses hidden by NAT.
Machines with an internal address may be accessed at the corresponding external valid IP address. See Figure
6-16.
Creating this relationship between internal and external addresses is done by defining internal and external
address ranges of equal length. Once that relationship is defined, the machine with the first internal address is
accessible at the first IP address in the external address range, and the second machine at the second external IP
address, and so on.
