Chapter 10: 

Configuring One-to-One NAT

One-to-One NAT maps valid, external addresses to private addresses hidden by NAT. Computers on 
your private LAN or OPT interface are accessed on the Internet at the corresponding public IP 
addresses.

You can create a relationship between internal and external addresses by defining internal and 
external address ranges. Once the relationship is defined, the computer with the first IP address of 
the private address range is accessible at the first IP address of the external address range, the 
second computer at the second external IP address, etc.

To configure One-to-One NAT, select the Network > One-to-One NAT page. 

To configure One-to-One NAT, complete the following instructions.

1 Select the Enable One-to-One NAT check box.

2 Click Add. The Add NAT Entry window is displayed.

3 Enter the beginning IP address of the private address range being mapped in the Private Range 

Start field. This is the IP address of the first machine that is accessible from the Internet.
