Internet Gateway 1.0

This is a single threaded WinpkFilter based Internet Connection sharing solution provided with complete source code*. It implements simple TCP and UDP dynamic NAT, what allows you to share the single Internet connection over your home network providing the major Internet services (e-mail, WWW, FTP** and etc...).

System requirements:

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

Version 1.0 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:

Internet Gateway is user mode WinpkFilter based application, so please refer our premium packet filtering library documentation for the complete details. User-mode part of Internet Gateway also utilize IP helper API for querying IP address information from the system.

How to use:

Server setup:

• Establish your Internet connection.

• Start Internet Gateway, you will see the dialog similar to the one below:

• Double-click the connection which is used for the Internet (on the screenshot below we connect Internet using dial-up modem). Set NAT status to "Provider" (you can choose one of the connection IP's for dynamic NAT). Click OK to finish.

• 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.
