Introduction to OpenVPN
OpenVPN is a versatile and robust open-source software VPN protocol that is used throughout the VPN industry. It comes in many forms though, and can require a bit of setup. Here is how you can get started with OpenVPN.
Understanding OpenVPN
When you connect to an OpenVPN server, the OpenVPN protocol encrypts your data, ensuring it remains secure. This protocol uses SSL/TLS for key exchange, leveraging the OpenSSL encryption library for robust security.
OpenVPN can operate over various ports and protocols, such as UDP and TCP, to bypass network restrictions and firewalls. It also supports traffic obfuscation to disguise VPN traffic as regular web traffic. The OpenVPN protocol is highly configurable, allowing for customised security settings and seamless integration across different devices and platforms.
Setting up OpenVPN
Windows 10 And Windows 11
Setting up OpenVPN on Windows 10 and 11 using an existing configuration file is straightforward. Follow these steps:
- Download and Install OpenVPN:
Go to the OpenVPN download page and download the installer for Windows. Run the installer and follow the prompts to complete the installation. Make sure to install the TAP drivers when prompted, as they are necessary for OpenVPN to function. - Obtain the Configuration Files:
Ensure you have the necessary .ovpn configuration file from your Members Area. This file contains all the settings required to connect to the VPN server. Typically, this configuration file will include server information, port, protocol, and necessary certificates and keys. - Place Configuration Files:
Copy the .ovpn configuration file to the OpenVPN config directory. By default, this is located at:
- C:\Program Files\OpenVPN\config
- If your configuration requires additional files such as certificates (.crt) or keys (.key), place them in the same directory. “`
- Run OpenVPN as Administrator:
OpenVPN needs administrative privileges to modify network settings. To do this, right-click the OpenVPN GUI shortcut and select “Run as administrator”. - Connect to the VPN:
Once the OpenVPN GUI is running, find the OpenVPN icon in the system tray (it looks like a computer monitor with a lock). Right-click the icon, you will see the list of available configuration files. Click on the configuration file you placed in the config directory and select “Connect”. - Enter Credentials (if required):
If your configuration file requires authentication, a dialogue box will prompt you to enter your username and password. Enter your hide.me VPN credentials. - Verify Connection:
Once connected, the OpenVPN icon in the system tray will turn green. You can verify your connection by checking your IP address on a website like our own or by checking the connection status in the OpenVPN GUI.
macOS
- Download Tunnelblick: Download Tunnelblick, an open-source graphic user interface for OpenVPN on macOS, from tunnelblick.net.
- Install Tunnelblick: Open the downloaded file and follow the installation instructions.
- Add Configuration: Place your .ovpn configuration file in the ~/Library/Application Support/Tunnelblick/Configurations directory.
- Connect: Launch Tunnelblick and connect using the imported configuration.
Android
- Download OpenVPN Connect: Install the OpenVPN Connect app from the Google Play Store.
- Import Configuration: Transfer your .ovpn file to your Android device and import it into the OpenVPN Connect app.
- Connect: Open the app, select the profile, and connect.
iOS
- Download OpenVPN Connect: Install the OpenVPN Connect app from the App Store.
- Import Configuration: Use iTunes, email, or another method to transfer the .ovpn file to your iOS device. Open it with OpenVPN Connect.
- Connect: Launch the app, select the profile, and connect.
Use OpenVPN with the hide.me VPN app
The hide.me VPN app is by far the easiest way to use OpenVPN on any device. All you have to do is download it for your device of choice and head to the Settings page.
In there, you will find a Protocol section that lists all the protocols the app supports. That includes OpenVPN in its TCP and UDP variants.
Key features of OpenVPN
OpenVPN Protocol
OpenVPN as a protocol is known for its robustness and flexibility. It supports various encryption algorithms, including those provided by the OpenSSL encryption library, and can encapsulate traffic using UDP or TCP.
Security and Encryption
OpenVPN provides strong security through the use of pre-shared secret keys, certificate-based authentication, and support for the TLS protocol. This ensures that data transmitted over the VPN is well-protected from interception and tampering.
Traffic Obfuscation
To avoid detection and blocking by network operators, OpenVPN supports traffic obfuscation. This feature helps mask VPN traffic as regular web traffic, making it harder for firewalls and ISPs to detect and block.
Common questions about OpenVPN
OpenVPN UDP vs TCP
OpenVPN can operate over both UDP and TCP. UDP is generally faster and more efficient for VPN connections, while TCP is more reliable and can better handle packet loss.
OpenVPN on Raspberry Pi
Raspberry Pi is a popular platform for running OpenVPN due to its low cost and energy efficiency. Setting up OpenVPN on a Raspberry Pi involves installing the OpenVPN package and configuring it through the command line.
OpenVPN Port Forwarding
Port forwarding with OpenVPN involves configuring your network to allow specific traffic to pass through the VPN. This can be necessary for applications that require incoming connections.
Is OpenVPN Safe?
Yes, OpenVPN is considered safe due to its use of strong encryption and secure protocols. However, the overall security also depends on the configuration and the security practices followed.
OpenVPN Alternatives
While OpenVPN is highly popular, alternatives like WireGuard has started to take over due to its efficiency and ease of use.
