Что такое адаптеры TAP-Windows и почему вашему VPN требуется этот драйвер

В этом посте рассказывается о адаптерах TAP-Windows , о том, что они собой представляют, зачем они нужны для VPN и где можно скачать драйверы TAP. Мы также покажем вам, как установить, обновить или удалить драйвер TAP.

Если вы откроете Настройки в Windows 10, вы увидите программу под названием TAP-Windows.

Пользователи Windows 10/8/7/Vista увидят его на панели управления .

Если вы откроете Диспетчер устройств и развернете Адаптеры, вы также увидите его там.

Что такое адаптеры TAP-Windows

TAP-Windows обеспечивает функциональность виртуального устройства TAP в ОС Windows. Он устанавливается в папку C: \ Program Files \ TAP-Windows и требуется для работы программного обеспечения VPN.

Устройства TAP – это устройства ядра виртуальной сети, полностью поддерживаемые программным обеспечением и не поддерживаемые аппаратными сетевыми адаптерами. Драйверы TAP используются для работы устройств TAP и имеют низкоуровневую поддержку ядра для туннелирования Ethernet.

Вам не нужно устанавливать TAP-окна отдельно, так как ваши установщики VPN включают их и устанавливают автоматически вместе с программным обеспечением VPN.

Драйвер TAP-Windows бывает двух типов:

1. NDIS 6 (TAP-windows6, версия 9.21.x) для Windows 10/8/7/Vista.
2. Драйвер NDIS 5 (TAP-windows, версия 9.9.x) для Windows XP.

Иногда вы можете столкнуться с проблемами , вызванными этим драйвером. Давайте посмотрим на некоторые из них.

Адаптеры TAP-Windows в этой системе в настоящее время используются

Если вы видите это сообщение или у вашего программного обеспечения VPN возникают проблемы с запуском, вы можете перезапустить адаптер TAP и посмотреть, поможет ли это. Для этого откройте Панель управления> Центр управления сетями и общим доступом> Нажмите «Изменить параметры адаптера», чтобы открыть «Сетевые подключения».

Вы увидите, что одно из локальных подключений будет иметь имя TAP-Windows Adapter . Щелкните правой кнопкой мыши по нему и выберите Отключить . Через несколько секунд снова щелкните его правой кнопкой мыши и выберите Включить . Теперь попробуйте подключиться снова и посмотреть, работает ли он.

Если у вас возникают другие проблемы с запуском вашего программного обеспечения VPN, я предлагаю вам открыть панель управления и оттуда либо восстановить , либо удалить и переустановить программное обеспечение VPN и посмотреть. Во время ремонта/установки будут установлены драйверы TAP.

Если вы хотите удалить, отключить или обновить TAP-Windows, из меню WinX Windows 10, откройте Диспетчер устройств и разверните Адаптеры, вы увидите Адаптер TAP-Windows v9.

Щелкните правой кнопкой мыши на нем, и вам предложат варианты обновить, отключить или удалить драйвер.

В этой системе нет адаптеров TAP-Windows

Если ваше программное обеспечение VPN не находит этот драйвер установленным на вашем компьютере, вы можете получить сообщение «В этом системном сообщении об ошибке отсутствуют адаптеры TAP-Windows». Затем вам нужно будет загрузить его настройки и установить драйвер.

Скачать драйвер адаптера TAP-Windows

Чтобы загрузить файл драйвера TAP-Windows, посетите openvpn.net. Прокрутите вниз, и вы увидите их ссылки для скачивания.

Запустите его установщик. После завершения установки драйвера перезагрузите компьютер и проверьте.

Если ваше Интернет-соединение перестает работать, вы можете удалить этот адаптер и посмотреть, поможет ли это вам. Если это не так, возможно, вам нужно удалить и переустановить последнюю версию этого драйвера заново .

О том что нужно не потерять

OpenVPN Error: All TAP-Windows adapters on this system are currently in use

Ошибка при попытке подключения к OpenVPN серверу.

Ошибка “All TAP-Windows adapters on this system are currently in use” означает что в системе проблемы с виртуальным Tun/Tap сетевым адаптером, который использует OpenVPN в Windows.

В моем случае он просто не появлялся в системе Windows7.

Для исправления проблемы нужно переустановить драйвер виртуального адаптера.

Полностью удаляем драйвер. Открываем папку C:\Program Files\TAP-Windows
Нажимаем правой кнопкой на файл Uninstall.exe и выбираем Запустить от имени администратора.

Качаем Tap драйвер с OpenVPN репозитория и устанавливаем его с правами админа (правый клик на файле > Запустить от имени администратора )

После всего обязательно заходим в Панель управления\Сеть и Интернет\Сетевые подключения и проверяем там наличие TAP-Windows Adapter.

спасибо. только это и помогло. вместе с удалением поделки касперского.

Списибо тебе, о Человек! Я пол часа ипался с сервером, думал что косяк в конфигах. Оказалось, что у меня не корректно установился клиент, без TAP-а. Почему люди не пишут, в своих статьях, что после установки клиента должен появиться туннельный адаптер.

Благодарствую тебе, о великий гуру!
Пол дня колупания в интернете и поиска дров для этого адаптера, а в условиях удаленки это прям оч важнецки!
Ещё раз спасибо!

Скинул на печеньку. Спасибо добрый ты человек!

Спасибо за ссылку на драйвер. У меня win7 и при установке vpnmonster ставятся драйвера без цифровой подписи под семёрку, в результате программа не работала. Установка данных драйверов помогла.

Блин, спасибо! У меня техподдержка на работе на эту проблему выдала, что винду надо переустановить, иначе не заработает.

Спасибо тебе добрый человек. Только этот рецепт и помог. Странно, что в дистрибутив OpenVPN включили неподписанный драйвер (пробовал версии 3.1.3.713 и 2.4.9-I601-Win7).

Спасибо большое! Меня тоже убедили, что переустановка Винды решит проблему, А нет:((

Спасибо огромное, тебе, добрый человек! Две минуты и все работает, а то сисадмин компании кинул на произвол судьбы, сказав, что не помнит как решить данную проблему!

Боже, присоединяюсь к людям в коммах, ты очень помог, брат, другие сайты не помогли

Спасибо! Все заработало. Два часа мучений и паники с переустановкой vpn в разных вариантах… Вы спасли.

О СПАСИТЕЛЬ. КО МНЕ УЖЕ ТУТ ХАКЕРЫ ПРИХОДИЛИ И ВСЕ КАК ОДИН ТВЕРДИЛИ, ТОЛЬКО СИСТЕМУ ПЕРЕУСТАНАВЛИВАТЬ ПРОБОВАТЬ! Спасибо большое, парень, ты реально спас. Отдельный тебе респект и почтенная благодарность, за прямую ссылку на скачивания драйвера, который я искал с хакерами целый день и ни хрена не нашел даже платно! РЕСПЕКТ ИЗ РЕСПЕКТОВ.

Добрый вечер. Пытаюсь подключиться к впн, пишет ошибку WARNING: normally if you use –mssfix and/or –fragment, you should also set –tun-mtu 1500 (currently it is 1400)
Че делать подскажите плиззз

OpenVPN 2.4.10 — Released 9 December, 2020

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.

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

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).

OpenVPN 2.4.9 — Released 17 April, 2020

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.

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.

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.

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.

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.

OpenVPN 2.4.6 — Released 24 April, 2018

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.

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. Our long-term plan is to migrate to using MSI installers instead.

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).
