NAT32 is a Microsoft Windows application that gives all computers on your private LANs direct Internet access via one or more Internet connections of any type. NAT32 runs only on the computer with the Internet connection(s) and acts as an enhanced IP Router for the other computers on your private networks. The computer running NAT32 can be fully isolated from the Internet, thus ensuring a secure operating environment.
NAT32 can also prevent machines from accessing sites specified in various user-defined name lists. This mechanism greatly enhances privacy and security for all applications, not just Web Browsers.
