Openvpn Connect Server Download
Lang Nunnally
Each Windows device needs a client application to connect with your OpenVPN Access Server. We recommend using OpenVPN Connect, which is pre-configured to connect with your Access Server. This document provides information on using OpenVPN Connect as well as alternative solutions.
The OpenVPN protocol is not built into Windows. Therefore, you must install a client app to handle communication with Access Server. A client app is required to capture the traffic you want to send through the OpenVPN tunnel, encrypt it, pass it on to the server, and decrypt the return traffic.
Your installation of OpenVPN Access Server includes a copy of OpenVPN Connect, which is a separate package called openvpn-as-bundled-clients that is updated when new versions of OpenVPN Connect are released. OpenVPN Connect is our official client app and your users can download it directly from your client UI, pre-configured to connect with your server, or download it separately from our website and import a connection profile.
OpenVPN Connect only supports one active VPN tunnel at a time. It was purposely designed to not support connections to two or more servers simultaneously. Connecting to two servers at the same time requires two different adjustments to the routing table on the client computer. Therefore, it is very easy to make a mistake and break connectivity or cause traffic to flow to the wrong destination. Limiting connections to one server ensures connectivity and traffic flow. OpenVPN Connect can store many profiles for different servers, but you can only actively connect to one at a time.
OpenVPN Connect also supports client-side scripting, importing connection profiles directly from Access Server, and connecting with a server-locked profile. A server-locked profile enables you to authenticate any valid user on your Access Server without installing unique connection profiles for each user.
We recommend and support OpenVPN Connect v3 as the official app for OpenVPN Access Server and OpenVPN Cloud. The client software offers client connectivity across four major platforms: Windows, macOS, Android, and iOS. For Linux, we recommend the open source OpenVPN client.
The open source project also has a Windows client called OpenVPN GUI. OpenVPN GUI supports the option to connect to multiple OpenVPN servers at the same time, but doing so requires careful configuration to avoid conflicting routes and subnets. Note that you must also make sure there are enough virtual network adapters. On Windows, OpenVPN creates a virtual network card or adapter, but only one OpenVPN tunnel can connect to a virtual network adapter. If you require three simultaneous OpenVPN tunnel connections, you must manually add adapters using command line scripts in the Start menu.
Similar to OpenVPN Connect v3, OpenVPN GUI also includes a service daemon mode where a connection starts up as a system service on Windows before the user is signed in. For more details, refer to Running OpenVPN as a Windows Service.
tunXten is a third-party client created by Eugene Mindrov. tunXten is only available for Windows and is compatible with OpenVPN Access Server. tunXten supports importing connection profiles directly from the Access Server and can also support multiple simultaneous OpenVPN tunnel connections. Just like the open source version, tunXten needs multiple virtual network adapters to do this, but it comes with a GUI tool to achieve this. You can simply keep adding adapters until you have the required number to establish as many connections as you need. It comes with useful logging information and the ability to place custom icons on connections, rename profiles in the GUI, set connections to automatically connect at boot up, remember saved usernames and passwords, and so on.
OpenVPN Access Server is compatible with most VPN clients that use the OpenVPN protocol. OpenVPN provides a free VPN client, OpenVPN Connect, to easily connect with your VPN server. Each implementation of Access Server also provides a Client UI, from which users can download pre-configured OpenVPN Connect apps and configuration files.
OpenVPN Access Server, our self-hosted VPN solution, simplifies the rapid deployment of a secure remote access and site-to-site solution with a web-based administration interface and built-in OpenVPN Connect app distribution with bundled connection profiles.
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.
The OpenVPN community project team is proud to release OpenVPN 2.4.11. 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. This release also includes other bug fixes and improvements. The I602 Windows installers fix a possible security issue with OpenSSL config autoloading on Windows (CVE-2021-3606). Updated OpenSSL and OpenVPN GUI are included in Windows installers.
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).
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.
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.
