VPN solution built with OpenVPN® Community Edition

Open Source VPN solution

OpenVPN® Community Edition provides a full-featured open source SSL/TLS Virtual Private Network (VPN). The TurnKey Linux VPN software appliance leverages the open source 'openvpn-server', 'openvpn-client' and 'easy-rsa' software (developed by OpenVPN® Inc.) to support "site-to-site" or "gateway" access. "Site-to-site" can link 2 otherwise unconnected LANs; suitable for multi-site enterprise networks or linkage to an Amazon VPC. "Gateway" configuration can secure traffic across public and/or insecure wifi connections and/or provide a secure solution for remote work scenarios.

Stable version: 16.0 (changelog)

This appliance includes all the standard features in TurnKey Core, and on top of that:

  • OpenVPN® configurations:
    • Initialization hooks to configure common OpenVPN® deployments such as "site-to-site" server or client and gateway profiles.
    • All profiles support SSL/TLS certificates for authentication and key exchange.
    • Server and gateway deployments include a convenience script to add clients, generating all required keys and certificates, as well as a unified ovpn profile for clients to easily connect to the VPN.
    • Expiring obfuscated HTTPS urls can be created for clients to download their profiles (especially useful with mobile devices using a QR code scanner).
    • The server profile supports a private subnet configuration, enabling clients to reach servers behind the OpenVPN® server.
    • The gateway profile configures connecting clients to tunnel all their traffic through the VPN.
    • When adding clients in a server or gateway deployment, an optional parameter can be given to enable computers on a subnet behind the client to connect to the VPN.
    • For added security, OpenVPN® is configured to drop privilages, run in a chroot jail dedicated to CRL, and uses tls-auth for HMAC signature verification protecting againsts DoS attacks, port flooding, port scanning and buffer overflow vulnerabilities in the SSL/TLS implementation.

Web - point your browser at either:

  1. http://12.34.56.789/ - not encrypted so no browser warning
  2. https://12.34.56.789/ - encrypted with self-signed SSL certificate
