OpenVPN is a lightweight open source VPN solution that is suitable for small to medium business needs. Please follow this tutorial to install and configure OpenVPN on Windows.
Download and install OpenVPN client for Windows:
Please follow this link to get to the OpenVPN download page:
Once you there please choose and download WINDOWS INSTALLER (NSIS) from the list of latest releases.
Please note: OpenVPN versions 2.4.x installers are built with a version of NSIS, which is known to have certain issues in older versions of Windows such as Windows 7. Starting versions 2.5.x OpenVPN will migrate to MSI installer. Until then, however, it is strongly recommended by OpenVPN team “to always move NSIS installers to a non-user-writable location before running them”. Detailed information is available on the download page at the link above. Please also note that OpenVPN 2.4.x will NOT work on Windows XP. Windows XP is supported by versions 2.3.18 and earlier (available as 32-bit and 64-bit versions).
Once you have downloaded the installer file, please go to the download folder and double-click the OpenVPN installation file. Depending on your settings Windows may ask for your permission to make changes on your PC. Please click Yes to continue.
Welcome screen of the OpenVPN Setup Wizard will appear. Please click Next to proceed.
You will be shown License Agreement. In order to continue you will need to accept the agreement by clicking I Agree.
In the next screen you can choose components to install (unless you want to make advanced changes you may leave the default selection). When done with selection please make sure you have enough space on your hard drive. Click Next.
You can now choose location for the OpenVPN files to be installed to. You may specify your own folder or leave the default location. This screen will also show you how much space will be occupied by OpenVPN. Click Install button to begin the installation process. Please wait for installation to finish.
Once the installation is completed please click Next.
The wizard is completed. Click Finish to close the window.
On your desktop please double-click the OpenVPN icon to start the client. Once OpenVPN is started its icon, an image of a computer with a lock, will appear in the Taskbar Notification area (at the bottom right of the screen) to indicate that it is running. At the first start the OpenVPN will pop up a message indicating that no VPN profile were found. Press OK.
