The WinpkFilter Device Driver
NAT32 Version 2 uses the WinpkFilter Device Driver for direct network I/O. On legacy platforms, this driver installs as an NDIS Intermediate Mode driver and supports most types of network interfaces up to NDIS Version 6.1. On current platforms, WinPkFilter installs as a Lightweight Filter Driver and supports most types of network interfaces up to NDIS Version 6.2 (including most 3G and UMTS adapters).
Be sure that Windows TCP/IP is correctly configured for all networking adapters before attempting to install WinpkFilter. You should be able to ping all your private machines and most Internet adresses from a Windows Console. If any machines can't be reached, please consult a local expert before continuing.
