OpenVPN 2.3.6 -- released on 2014.12.01 (Change Log)

This release fixes a critical denial of service vulnerability in OpenVPN servers (CVE-2014-8104). The vulnerability can only be exploited by authenticated clients. Also note that confidentiality and authenticity of traffic are not affected. More information about this vulnerability is available on the Trac wiki. This release includes a few other fixes and enhancements. A full list of changes is available here

Windows installers I002 and I602 bundle OpenSSL 1.0.1l, which fixes the FREAK vulnerability. The impact of the vulnerability on OpenVPN is discussed in detail in the Wiki. Windows installers I003 and I603 bundle OpenSSL 1.0.1m that fixes several security vulnerabilities, one of which (CVE-2015-0286) is likely to affect OpenVPN also.

If you find a bug in this release, please file a bug report to our Trac bug tracker. In uncertain cases please contact our developers first, either using the openvpn-devel mailinglist or the developer IRC channel (#openvpn-devel at For generic help take a look at our official documentation, wiki, forums, openvpn-users mailing list and user IRC channel (#openvpn at

OpenVPN 2.3.2 -- released on 2013.06.03 (Change Log)

This is an old point release and you should in general use OpenVPN 2.3.4 instead. However, as OpenVPN 2.3.4 contains a few potentially disruptive changes you may want to use this older release instead. Windows I004 installers included a fix for the very serious heartbleed vulnerability (OpenVPN-specifics here). Windows I005 installers bundle OpenSSL 1.0.0h, which fixes severe security issues. Windows installer I006 bundles OpenSSL 1.0.1i, which fixes several vulnerabilities.

All Windows users of OpenVPN 2.3.2 should upgrade to latest 2.3.2 or 2.3.4 release immediately.

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 for Windows XP and NDIS 6 for Windows and above. Source code for both tap-windows drivers is available on GitHub.

Installer (NDIS 5) tap-windows-9.9.2_3.exe GnuPG Signature
Installer (NDIS 6) tap-windows-9.21.1.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.

LZO RPM Packages
