Openvpn Vista Patch
Subject: Re: Openvpn-users TAP driver updates for XP64 and Vista; From: James Yonan jim xxxxxxxxx The TAP driver has Henry Nestler s patch for 32 bit Vista.
OpenVPN GUI is a graphical front-end application for OpenVPN on Windows. It gives you an icon in the system tray from which you can control OpenVPN.
Changes for running TAP-Win32 on Vista Beta :
- Gets MiniPortName with function NdisReadConfiguration, instand the
direct pointer access into strcture NDIS_MINIPORT_BLOCK.
On Windows2000 this function isn t supported, it falls back into
older accessing with ugly pointer into the struct. Checks ndis
version before, to avoid BSOD.
- incrase driver version to 8.4, updated build date.
openvpn-2.1-tap32-vista.patch : Source patch for openvpn-2.1_beta14
tap-win32-OpenVPN.src.zip : Complete sources for tap driver
tap-win32-OpenVPN.i386.zip : Driver, binary and symbols for OpenVPN
This is a backport from running tap driver under colinux.
Binaries for OpenVPN have not tested, I have no vpn installed. Please
Thanks to Emre Erenoglu and Anoop G. for finding, testing and tips.
