Step-by-Step OpenVPN Server Installation & Setup

Step 1: Deploying the Server

Choosing an Image

  • Use the OpenVPN server image from the official Marketplace (or any pre-configured image) to quickly launch the system.
  • This streamlines deployment and reduces setup time.

Receiving Login Credentials

  • After server creation, an instruction manual with login credentials will be available in your personal account.

Step 2: Accessing the Web Interface

Open your browser and enter the IP address of your deployed OpenVPN server. For example:

http://11.00.44/

If you receive a security certificate warning, allow the connection—this is normal for self-signed certificates on a test or newly deployed server. image5

Step 3: Logging In

For the first login, use the credentials provided after deployment.

  • The default username may be:

    Administrator

  • The password can be found in the installation instructions or retrieved from the server using:

    cat /root/.password_credentials

Once logged in, you'll gain full access to the OpenVPN management panel. image5

Additional Security & Scaling Tips

  • Use Strong Passwords: Avoid simple or easily guessable passwords. Secure credentials significantly reduce the risk of unauthorized access.
  • Regular Updates: Keep track of new OpenVPN releases. Updating both the server and client software helps fix vulnerabilities and improve stability.
  • Advanced Authentication: For tighter access control in a corporate environment, consider integrating OpenVPN with LDAP, RADIUS, or multi-factor authentication (MFA).
