Windows Packet Filter Kit (WinpkFilter) is a high performance packet filtering framework for Windows 9x/ME/NT/2000/XP/2003/Vista/2008/7/2008R2/8/2012/8.1/2012R2 that allows developers to transparently filter (i.e. view and modify) raw network packets on NDIS level with minimal impact on network activity & without having to write low level TDI or NDIS driver code.
With WinpkFilter, you can make an application that inserts itself into the Windows network packets flow: custom firewall solution, internet connection sharing (NAT), IP shaper, VPN and many other low-level network solutions completely in user-mode using your favorite development environment: Visual C++, Delphi, Visual Basic, C++ Builder, and etc.
Using WinpkFilter requires no experience in kernel mode programming on your behalf since WinpkFilter provides you with powerful user level API. However, if you need to implement your solution (to achieve better performance) in kernel mode you can do that as well on the base of WinpkFilter driver's code.
WinpkFilter supports Dial-Up connections (Analog modem, ISDN modem), Ethernet (LAN and WLAN) connections, Cable/DSL modem using DHCP or "PPP over Ethernet" (EnterNet, RasPPPoE, WinPoET), Mobile Broadband.
