NAT Server 2.0

This is a single threaded Internet Connection sharing solution. It implements TCP, UDP  and ICMP dynamic NAT, what allows you to share the single Internet connection over your network providing the major Internet services (e-mail, WWW, FTP** and etc...).Translate TCP, UDP and ICMP protocols.

System requirements:

Windows 98, ME, 2000, XP, 2003, Vista, 2008. Windows 7

Version 2.0 does not support WIndows NT 4.0 and Windows 95 because these operating systems miss GetAdaptersInfo routine from IP Helper API (it's used for obtaining IP configuration information). We plan to add support for these legacy operating systems in the future (getting the same information is possible but a bit trickier).

How it works:

NAT Server is user mode Ndis packet filter  based application, so please refer Microsoft packet filtering library documentation for the complete details.

• Double-click your home network interface and set its NAT status to "Client". Click OK

• Start dynamic NAT thread by clicking to "Start NAT" button.

Client setup:

You have to configure systems in your home network by assigning IP's statically or using DHCP. Default gateway address and DNS address should be set to the IP of the Server network interface connected to the home network. In the sample above systems in the home network should have IP from 10.0.0.0/24 and DNS/default gateway set to 10.0.0.1.

*** - For Windows Vista and later versions of the Windows family of operating systems, kernel-mode software must have a digital signature to load on x64-based computer systems. WinpkFilter drivers are not signed and in order to test them on Vista x64 you should press F8 during system boot and choose Disable Driver Signature Enforcement option.
