2. Manual configuration with the standard OpenVPN client: Designed for those who want more control or to create a custom private network (for example, between an office and home or to connect a Synology/QNAP NAS).

Below, we detail the steps for both methods on the most common operating systems (Windows, macOS, Linux, Android, and iOS).

How to use preconfigured clients for major VPN services

The vast majority of paid VPN providers offer their own apps for Windows, macOS, Linux, Android and iOS. Once the application is installed:

1. Launch the app and log in with your account.
2. Accede to Settings > Security > Protocol and select openvpn.
3. Choose the desired server from the list and press “Connect.”

From that moment on, All your internet traffic travels encrypted via OpenVPN. The app will automatically manage settings and reconnect if the connection drops.

Advanced or manual OpenVPN configuration on computer and mobile

The manual method is ideal if you want more customization, want to use your own server (for example, an ASUS router or Synology NAS), or if your provider doesn't offer its own client. The process involves downloading .ovpn configuration files and performing a few additional steps:

Configuring OpenVPN on Windows

1. Download the official OpenVPN client for Windows from openvpn.net/community-downloads or from your VPN provider's website.
2. Download the configuration files (.ovpn) OpenVPN from your VPN provider's download section (NordVPN, ExpressVPN, CyberGhost, etc.). If you're using your own server, generate these settings from the admin panel of your NAS or router.
3. Install the OpenVPN client and follow the wizard (usually just click “Next” and “Accept” the terms).
4. Once installed, move the .ovpn files to the “config” folder located inside the OpenVPN installation directory (usually in Program Files > OpenVPN > config).
5. Launch the OpenVPN GUI application. You'll see its icon in the system tray.
6. Right-click on the icon and choose the server profile you want to connect to.
7. When prompted, enter your username and password (provided by the VPN service or defined when setting up your own server).
8. When the connection is successful, a notification or color change will appear on the icon.

This procedure allows you to import as many .ovpn configurations as you want and use them on demand depending on the network or server you want to use (for example, work, home, international servers, etc.).

Setting up OpenVPN on macOS
