OpenVPN -- Older Releases

Older OpenVPN releases not explicitly listed above can be downloaded from here (alternate link).

WARNING: The Windows installers for these old releases may contain OpenSSL versions that have the heartbleed vulnerability or other serious security issues. You should not use any of these old OpenVPN Windows installers, unless you are absolutely sure it's safe in your use case. If you depend on an old OpenVPN version make sure you build the Windows binaries yourself and link them to an up-to-date OpenSSL version.

OpenVPN -- Packages and ports

OpenVPN is available in repositories of most open source operating systems such as Debian, Ubuntu, Fedora, FreeBSD and Maemo. Some of them may have several versions available, e.g. one for latest beta branch, one for latest development code and one for stable releases. Using these OS-provider versions is usually easiest. However the OpenVPN project also packages latest OpenVPN releases for some open source operating systems. Take a look here to see if these packages are available for your OS.


OpenVPN uses TAP-windows to provide virtual tap device functionality on Windows. Normally you don't need to install TAP-windows separately, as OpenVPN installers include it. The tap-windows driver comes in two flavours: the NDIS 5 driver (tap-windows, version 9.9.x) for Windows XP and NDIS 6 (tap-windows6, version 9.21.x) for Windows and above. Source code for both tap-windows drivers is available on GitHub.

NOTE: If you have 9.9.x installed, you need to uninstall it before installing 9.21.x, as there are known issues with doing an upgrade.

Installer (NDIS 5) tap-windows-9.9.2_3.exe GnuPG Signature
Installer (NDIS 6) tap-windows-9.21.2.exe GnuPG Signature

Most other operating systems have virtual tap device functionality in their kernels.


Starting with openvpn-2.3_alpha2 easy-rsa is no longer part of the OpenVPN source or binary packages. It can be downloaded separately from it's GitHub project page.


Official Windows binary packages are cross-compiled on Linux using mingw_w64 and the openvpn-build buildsystem. For details, look at the Wiki documentation.
