Openvpn tun driver windows 7

The OpenVPN community project team is proud to release OpenVPN 2.6.6. This is a small bugfix release.

For details see ​Changes.rst

User visible changes:

• OCC exit messages are now logged more visibly See GH ​#391.
• OpenSSL error messages are now logged with more details (for example, when loading a provider fails, which .so was tried, and why did it fail) See GH ​#361.
• print a more user-friendly message when tls-crypt-v2 client auth fails
• packaging now includes all documentation in the source tarball

New features:

• set WINS server via interactive service — this adds support for «dhcp-option WINS 192.0.2.1» for DCO + wintun interfaces where no DHCP server is used. See GH ​#373.

Windows MSI changes since 2.6.5:

• Included openvpn-gui updated to 11.44.0.0
• MSIs now use OpenSSL 3.1.2

For Community-maintained packages for Linux distributions see OpenvpnSoftwareRepos

The OpenVPN community project team is proud to release OpenVPN 2.6.4. This is a small bugfix release.

For details see ​Changes.rst

Note:

• License amendment: all new commits fall under a modified license that explicitly permits linking with Apache2 libraries (mbedTLS, OpenSSL) — see COPYING for details. Existing code will fall under the new license as soon as all contributors have agreed to the change — work ongoing.

Feature changes:

• DCO: support kernel-triggered key rotation (avoid IV reuse after 2³² packets). This is the userland side, accepting a message from kernel, and initiating a TLS renegotiation. As of 2.6.4 release, only implemented in FreeBSD kernel.

Windows MSI changes since 2.6.3:

• Rebuilt included tap-windows driver with the correct version of the old Windows 7 driver, removing a warning about unsigned driver on Windows 7 installation. See GH ​openvpn-build#365.

The OpenVPN community project team is proud to release OpenVPN 2.6.3. This is a small bugfix release.

For details see ​Changes.rst

Feature changes:

• Windows: support setting DNS domain in configurations without GUI and DHCP (typically wintun or windco drivers), see GH ​openvpn#306.

Windows MSI changes since 2.6.2:

• Several Windows-specific issues fixed:
  • ensure interactive service stays enabled after silent reinstall, see GH ​openvpn-build#348, ​openvpn-build#349 and ​openvpn-build#351
  • repair querying install path info for easyrsa-start.bat on some Windows language versions, see GH ​openvpn-build#352.
• MSIs are now built against OpenSSL 3.1.0.
• Update included openvpn-gui to 11.41.0.0
  • This update removes the ability to change the password of a private key from the GUI. This was a niche feature which caused a direct dependency of GUI on OpenSSL. Use openssl.exe directly if you need to edit a private key.

Note: Windows MSI was updated to I003 on April 26th. Changes in I003:

• The GPG subkey for creating the .asc files for the downloads has been updated. You might need to re-download or update the GPG key if verifying the signatures.
• Fix the encoding of some documentation/sample files included in the installer. See GH ​openvpn-build#358
• Update include tap-windows6 driver to 9.25.0
  • Fixes a problem with sending small non-IP packets (e.g. PPPoE) over the VPN connection. See GH ​tap-windows6#158
  • Note: The new driver is only used on Windows 10 and newer. We can’t rebuild drivers for Windows 7/8 since Microsoft doesn’t support the signing mechanism anymore. We include the previous driver version to still allow installation on Windows 7/8.
• Update included openvpn-gui to 11.42.0.0
  • Fixes a problem with passphrase prompt was sometimes not displayed. See GH ​openvpn-gui#619
  • Adds «Password Reveal» feature which allows you to see passwords while entering them.

The OpenVPN community project team is proud to release OpenVPN 2.6.2. This is mostly a bugfix release with some improvements.

For details see ​Changes.rst

Feature changes:

• implement byte counter statistics for DCO Linux (p2mp server and client)
• implement byte counter statistics for DCO Windows (client only)
• --dns server <n> address ... now permits up to 8 v4 or v6 addresses

Important note for Linux DCO users:

• New control packets flow for data channel offloading on Linux: 2.6.2+ changes the way OpenVPN control packets are handled on Linux when DCO is active, fixing the lockups observed with 2.6.0/2.6.1 under high client connect/disconnect activity. This is an INCOMPATIBLE change and therefore an ovpn-dco kernel module older than v0.2.20230323 (commit ID 726fdfe0fa21) will not work anymore and must be upgraded. The kernel module was renamed to «ovpn-dco-v2.ko» in order to highlight this change and ensure that users and userspace software could easily understand which version is loaded. Attempting to use the old ovpn-dco with 2.6.2+ will lead to disabling DCO at runtime.

Windows MSI changes since 2.6.1:

• Update included openvpn-gui to 11.39.0.0

The OpenVPN community project team is proud to release OpenVPN 2.6.1. This is mostly a bugfix release with some improvements.

For details see ​Changes.rst

Feature changes:

• Dynamic TLS Crypt: When both peers are OpenVPN 2.6.1+, OpenVPN will dynamically create a tls-crypt key that is used for renegotiation. This ensure that only the previously authenticated peer can do trigger renegotiation and complete renegotiations.
• CryptoAPI (Windows): support issuer name as a selector. Certificate selection string can now specify a partial issuer name string as
  «—cryptoapicert ISSUER:<string>» where <string> is matched as a substring of the issuer (CA) name in the certificate.

Note: configure now enables DCO build by default on FreeBSD and Linux. On Linux this brings in a new default dependency for libnl-genl (for Linux distributions that are too old to have a suitable version of the library, use «configure —disable-dco»)

Windows MSI changes since 2.6.1:

• Update included ovpn-dco-win driver to 0.9.2

The OpenVPN community project team is proud to release OpenVPN 2.6.0. This is a new stable release with some major new features.

For details see: Changes.rst

The Changes document also contains a section with workarounds for common problems encountered when using OpenVPN with OpenSSL 3.

New features and improvements in 2.6.0 compared to 2.5.8:

• Data Channel Offload (DCO) kernel acceleration support for Windows, Linux, and FreeBSD.
• OpenSSL 3 support.
• Improved handling of tunnel MTU, including support for pushable MTU.
• Outdated cryptographic algorithms disabled by default, but there are options to override if necessary.
• Reworked TLS handshake, making OpenVPN immune to replay-packet state exhaustion attacks.
• Added —peer-fingerprint mode for a more simplistic certificate setup and verification.
• Added Pre-Logon Access Provider support to OpenVPN GUI for Windows.
• Improved protocol negotiation, leading to faster connection setup.
• Included openvpn-gui updated to 11.37.0.0. See CHANGES.rst.
• Updated easy-rsa3 bundled with the installer on Windows.
• Various bug fixes.

The OpenVPN community project team is proud to release OpenVPN 2.5.4. This release include a number of fixes and small improvements. One of the fixes is to password prompting on windows console when stderr redirection is in use — this breaks 2.5.x on Win11/ARM, and might also break on Win11/amd64. Windows executable and libraries are now built natively on Windows using MSVC, not cross-compiled on Linux as with earlier 2.5 releases. Windows installers include updated OpenSSL and new OpenVPN GUI. The latter includes several improvements, the most important of which is the ability to import profiles from URLs where available. Installer version I602 fixes loading of pkcs11 files on Windows. Installer version I603 fixes a bug in the version number as seen by Windows (was 2.5..4, not 2.5.4). Installer I604 fixes some small Windows issues.

BF-CBC cipher is no longer the default

Cipher handling for the data channel cipher has been significantly changed between OpenVPN 2.3/2.4 and v2.5, most notably there are no «default cipher BF-CBC» anymore because it is no longer considered a reasonable default. BF-CBC is still available, but it needs to be explicitly configured now.

For connections between OpenVPN 2.4 and v2.5 clients and servers, both ends will be able  to negotiate a better cipher than BF-CBC. By default they will select one of the AES-GCM ciphers, but this can be influenced using the —data-ciphers setting.

Connections between OpenVPN 2.3 and v2.5 that have no —cipher setting in the config (= defaulting to BF-CBC and not being negotiation-capable) must be updated. Unless BF-CBC is included in —data-ciphers or there is a «—cipher BF-CBC» in the OpenVPN 2.5 config, a v2.5 client or server will refuse to talk to a v2.3 server or client, because it has no common data channel cipher and negotiating a cipher is not possible. Generally, we recommend upgrading such setups to OpenVPN 2.4 or v2.5. If upgrading is not possible we recommend adding data-ciphers AES-256-GCM:AES-128-GCM:AES-128-CBC (for v2.5+) or cipher AES-128-CBC (v2.4.x and older) to the configuration of all clients and servers.

If you really need to use an unsupported OpenVPN 2.3 (or even older) release and need to stay on BF-CBC (not recommended), the OpenVPN 2.5 based client will need a config file change to re-enable BF-CBC.  But be warned that BF-CBC and other related weak ciphers will be removed in coming OpenVPN major releases.

Connectivity to some VPN service provider may break

Connecting with an OpenVPN 2.5 client to at least one commercial VPN service that

implemented their own cipher negotiation method that always reports back that it is using BF-CBC to the client is broken in v2.5. This has always caused warning about mismatch ciphers. We have been in contact with some service providers and they are looking into it.  This is not something the OpenVPN community can fix.  If your commercial VPN does not work with a v2.5 client, complain to the VPN service provider.

More details on these new features as well as a list of deprecated features and user-visible changes are available in Changes.rst.

The OpenVPN community project team is proud to release OpenVPN 2.5.3. Besides a number of small improvements and bug fixes, this release fixes a possible security issue with OpenSSL config autoloading on Windows (CVE-2021-3606). Updated OpenVPN GUI is also included in Windows installers.

The OpenVPN community project team is proud to release OpenVPN 2.5.2. It fixes two related security vulnerabilities (CVE-2020-15078) which under very specific circumstances allow tricking a server using delayed authentication (plugin or management) into returning a PUSH_REPLY before the AUTH_FAILED message, which can possibly be used to gather information about a VPN setup. In combination with «—auth-gen-token» or a user-specific token auth solution it can be possible to get access to a VPN with an otherwise-invalid account. OpenVPN 2.5.2 also includes other bug fixes and improvements. Updated OpenSSL and OpenVPN GUI are included in Windows installers.

Updated OpenSSL and OpenVPN GUI are included in Windows installers.

A summary of the changes is available in Changes.rst, and a full list of changes is available here.

Please note that LibreSSL is not a supported crypto backend. We accept patches and we do test on OpenBSD 6.0 which comes with LibreSSL, but if newer versions of LibreSSL break API compatibility we do not take responsibility to fix that.

Also note that Windows installers have been built with NSIS version that has been patched against several NSIS installer code execution and privilege escalation problems. Based on our testing, though, older Windows versions such as Windows 7 might not benefit from these fixes. We thus strongly encourage you to always move NSIS installers to a non-user-writeable location before running them.

Please note that OpenVPN 2.4 installers will not work on Windows XP. The last OpenVPN version that supports Windows XP is 2.3.18, which is downloadable as 32-bit and 64-bit versions.

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 irc.libera.chat). For generic help take a look at our official documentation, wiki, forums, openvpn-users mailing list and user IRC channel (#openvpn at irc.libera.chat).

Important: you will need to use the correct installer for your operating system. The Windows 10 installer works on Windows 10 and Windows Server 2016/2019. The Windows 7 installer will work on Windows 7/8/8.1/Server 2012r2. This is because of Microsoft’s driver signing requirements are different for kernel-mode devices drivers, which in our case affects OpenVPN’s tap driver (tap-windows6).

This is primarily a maintenance release with bugfixes and small improvements. Windows installers include the latest OpenSSL version (1.1.1i) which includes security fixes.

The Windows installers are bundled with OpenVPN-GUI — its source code is available on its project page and as tarballs on our alternative download server.

This is primarily a maintenance release with bugfixes and improvements. This release also fixes a security issue (CVE-2020-11810, trac #1272) which allows disrupting service of a freshly connected client that has not yet not negotiated session keys. The vulnerability cannot be used to inject or steal VPN traffic.

We are moving to MSI installers in OpenVPN 2.5, but OpenVPN 2.4.x will remain NSIS-only.

Compared to OpenVPN 2.3 this is a major update with a large number of new features, improvements and fixes. Some of the major features are AEAD (GCM) cipher and Elliptic Curve DH key exchange support, improved IPv4/IPv6 dual stack support and more seamless connection migration when client’s IP address changes (Peer-ID). Also, the new —tls-crypt feature can be used to increase users’ connection privacy.

OpenVPN GUI bundled with the Windows installer has a large number of new features compared to the one bundled with OpenVPN 2.3. One of major features is the ability to run OpenVPN GUI without administrator privileges. For full details, see the changelog. The new OpenVPN GUI features are documented here.

You can use EasyRSA 2 or EasyRSA 3 for generating your own certificate authority. The former is bundled with Windows installers. The latter is a more modern alternative for UNIX-like operating systems.

The Windows installers are bundled with OpenVPN-GUI — its source code is available on its project page and as tarballs on our alternative download server.

This is primarily a maintenance release with bugfixes and improvements. The Windows installers (I601) have several improvements compared to the previous release:

• New tap-windows6 driver (9.24.2) which fixes some suspend and resume issues
• Latest OpenVPN-GUI
• Considerable performance boost due to new compiler optimization flags

This release is also available in our own software repositories for Debian and Ubuntu, Supported architectures are i386 and amd64. For details. look here.

You can use EasyRSA 2 or EasyRSA 3 for generating your own certificate authority. The former is bundled with Windows installers. The latter is a more modern alternative for UNIX-like operating systems.

The Windows installers are bundled with OpenVPN-GUI — its source code is available on its project page and as tarballs on our alternative download server.

This is primarily a maintenance release with bugfixes and improvements. One of the big things is enhanced TLS 1.3 support. A summary of the changes is available in Changes.rst, and a full list of changes is available here.

Please note that LibreSSL is not a supported crypto backend. We accept patches and we do test on OpenBSD 6.0 which comes with LibreSSL, but if newer versions of LibreSSL break API compatibility we do not take responsibility to fix that.

Also note that Windows installers have been built with NSIS version that has been patched against several NSIS installer code execution and privilege escalation problems. Based on our testing, though, older Windows versions such as Windows 7 might not benefit from these fixes. We thus strongly encourage you to always move NSIS installers to a non-user-writeable location before running them. We are moving to MSI installers in OpenVPN 2.5, but OpenVPN 2.4.x will remain NSIS-only.

Compared to OpenVPN 2.3 this is a major update with a large number of new features, improvements and fixes. Some of the major features are AEAD (GCM) cipher and Elliptic Curve DH key exchange support, improved IPv4/IPv6 dual stack support and more seamless connection migration when client’s IP address changes (Peer-ID). Also, the new —tls-crypt feature can be used to increase users’ connection privacy.

OpenVPN GUI bundled with the Windows installer has a large number of new features compared to the one bundled with OpenVPN 2.3. One of major features is the ability to run OpenVPN GUI without administrator privileges. For full details, see the changelog. The new OpenVPN GUI features are documented here.

Please note that OpenVPN 2.4 installers will not work on Windows XP. The last OpenVPN version that supports Windows XP is 2.3.18, which is downloadable as 32-bit and 64-bit versions.

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 irc.libera.chat). For generic help take a look at our official documentation, wiki, forums, openvpn-users mailing list and user IRC channel (#openvpn at irc.libera.chat).

Important: you will need to use the correct installer for your operating system. The Windows 10 installer will not work on Windows 7/8/8.1/Server 2012r2. This is because Microsoft’s driver signing requirements and tap-windows6. For the same reason you need to use an older installer with Windows Server 2016. This older installer has a local privilege escalation vulnerability issue which we cannot resolve for Windows Server 2016 until tap-windows6 passes the HLK test suite on that platform. In the meanwhile we recommend Windows Server 2016 users to avoid installing OpenVPN/tap-windows6 driver on hosts where all users can’t be trusted. Users of Windows 7-10 and Server 2012r2 are recommended to update to latest installers as soon as possible.

This is primarily a maintenance release with minor bugfixes and improvements, and one security relevant fix for the Windows Interactive Service. Windows installer includes updated OpenVPN GUI and OpenSSL. Installer I601 included tap-windows6 driver 9.22.1 which had one security fix and dropped Windows Vista support. However, in installer I602 we had to revert back to tap-windows 9.21.2 due to driver getting reject on freshly installed Windows 10 rev 1607 and later when Secure Boot was enabled. The failure was due to the new, more strict driver signing requirements. The 9.22.1 version of the driver is in the process of getting approved and signed by Microsoft and will be bundled in an upcoming Windows installer.

You can download Windows developments snapshots (MSI installers) from here (Index of /downloads/snapshots/github-actions/openvpn2/ ). Those are automatically built from commits to OpenVPN master branch and include functionality which will be available in the next release. Development snapshots are less stable than releases, so use at your own risk.
