Questions tagged [openvpn]

Free software implementing virtual private networks (VPN). **Important:** This tag is exclusively for programming-related questions, NOT for general questions on configuring or using VPNs; questions about general network and server administration should be directed to Server Fault, and questions about general software use should be directed to Super User.

OpenVPN is an open source software application that implements virtual private network (VPN) techniques for creating secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities. OpenVPN allows peers to authenticate each other using a pre-shared secret key, certificates, or username/password.

In contrast to traditional VPN which uses IPSec/IP protocol (with which many home routers and firewalls have issues), it uses TLS over TCP/IP and UDP/IP protocols.
