12/25 OpenVPN is an SSL VPN solution which can accommodate a wide
range of configurations, including remote access, site-to-site VPNs,
WiFi security, and remote access solutions with load
balancing, failover, and fine-grained access-controls.
OpenVPN implements OSI layer 2 or 3 secure network extension using the
SSL/TLS protocol, supports flexible client
authentication methods based on certificates, smart cards, and/or
2-factor authentication, and allows user or group-specific access
control policies using firewall rules applied to the VPN virtual
interface.
OpenVPN is not a web application proxy and does not operate through a
web browser.
