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.
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
Create secure ethernet bridges using virtual tap devices
Control OpenVPN using a GUI on Windows or Mac OS X.
