HOW TO install/uninstall the WinPkFilter Device Driver and the NAT32 Certificate
The WinPkFilter driver is implemented as a Network Service that can be installed either manually, as outlined here, or from within NAT32 via the following commands:
driver install driver uninstall
On most platforms, once the driver has been installed, simply restart to configure NAT32.
To update the driver, uninstall the existing driver, reboot Windows and then install the new driver.
The driver itself is contained in a file called ndisrd.sys and various versions of this file exist, one for each specific platform and driver technology. During installation, the installer may prompt for the location of the ndisrd.sys file. If so, consult the following directory tree for the location of the needed version:
C:\NAT32v2\Drivers\ HOOKDRV # Hooking driver for 32-bit Windows XP Pre-SP3 systems only. # Use this command to install: driverx install IMDRV # Intermediate drivers for Windows XP, Server 2003 WIN32 # 32-bit version X64 # 64-bit version LWF # Lightweight filter drivers for Windows 7, 8 and Vista WIN7_32 # Windows 7 32-bit version WIN7_64 # Windows 7 64-bit version WIN8_32 # Windows 8 32-bit version WIN8_64 # Windows 8 64-bit version WINV_32 # Vista 32-bit version WINV_64 # Vista 64-bit version
Prudent users will also install the NAT32 Certificate in order to verify the authenticity of downloads from the NAT32.COM website. This can be done in the NAT32 Console as follows:
The SHA1 hash for the certificate is: B5044BF745E7821FCE1D4DBCE71642F62D593388
