Many home and small business users have private local area networks with only a single computer connected to the Internet.
NAT32® is a Microsoft Windows® application which gives all computers on your private LANs direct Internet access. NAT32 runs only on the computer with the Internet connection and acts as an enhanced IP Router for the other computers on your private networks. The computer running NAT32 retains totally unmodified Internet access, and all applications on that computer will continue to run as before. On your other computers, most of your networking applications will require no reconfiguration, they simply pass all Internet packets to the NAT32 router, which forwards them to the Internet.

NAT32 supports Connection Sharing of Modems, ISDN Adapters, ADSL Adapters and Cable Modems. Each of your private computers is configured to use the NAT32 Router's unique private IP address as its DNS Server and Default Gateway. NAT32's built-in DHCP Server can configure the private computers automatically if you set them to "Obtain an IP address automatically" in Control Panel, Network, TCP/IP Properties.

NAT32® is available in two different versions: NAT32 Standard and NAT32 Enhanced.
NAT32 Enhanced has a new, simplified user interface called the Quick Dialog. Toolbar Icons let you select commonly needed features with a single mouse click. A list box displays the most important NAT32E Settings. To test and modify those settings, simply double-click the desired list box entry to access its configuration dialog box.

The details in the Quick Dialog are updated dynamically, giving you instant feedback if a connection goes down, a Name Server has failed or any other important settings have changed.

A Progress Bar shows the current throughput for each Internet adapter NAT32E is currently using.

NAT32E  is the only package of its kind to offer a full-featuredPPPoE Server Testbed for Windows 98/ME/2000/XP platforms. This feature works in conjunction with the RASPPPoE driver and allows tracing and debugging of PPPoE traffic.

NAT32E is the only package of its kind to fully support multiple Internet Interfaces, multiple private LANs and multiple private LAN gateways. It surpasses Microsoft® Internet Connection Sharing in both performance and flexibility and is well-suited for use in large networks with complex private LAN topologies.

NAT32E is now compatible with Windows ICS. Use ICS to share one Internet Connection and NAT32E to share other Internet Connections.

All versions of NAT32 fully support the Windows Dial-Up Networking Server in TCP/IP mode. Run NAT32 on your Office machine and then dial in from home to access the Internet. No more busy tones, poor throughput or monthly ISP charges!
