OpenVPN is designed to be a full-featured SSL VPN solution that can accommodate a wide range of configurations. Pritunl available for profile management.

These include remote access, site-to-site VPNs, WiFi security, and enterprise-scale remote access solutions with load balancing.

OpenVPN implements OSI layer 2 or 3 secure network extensions using the industry-standard SSL/TLS protocol, supports flexible client authentication methods based on certificates, smart cards, and/or 2-factor authentication, and allows users group-specific access control policies using firewall rules applied to the VPN virtual interface. This utility is not a web application proxy and does not operate through a web browser.

OpenVPN Features:

Tunnel any IP subnetwork or virtual ethernet adapter over a single UDP or TCP port

Configure a scalable, load-balanced VPN server farm using one or more machines that can handle thousands of dynamic connections from incoming VPN clients

Use all of the encryption, authentication, and certification features of the OpenSSL library to protect your private network traffic as it transits the internet

Use any cipher, key size, or HMAC digest (for datagram integrity checking) supported by the OpenSSL library

Choose between static-key-based conventional encryption or certificate-based public-key encryption

Use static, pre-shared keys or TLS-based dynamic key exchange

Use real-time adaptive link compression and traffic-shaping to manage link bandwidth utilization

Tunnel networks whose public endpoints are dynamic, such as DHCP or dial-in clients

Tunnel networks through connection-oriented stateful firewalls without having to use explicit firewall rules

Tunnel networks over NAT
