Port :1194OpenVPN

OpenVPN is an open-source virtual private network (VPN) solution known for its flexibility and strong security features. It is designed to operate over both TCP and UDP transport protocols, providing adaptability based on network requirements. OpenVPN uses a custom security protocol that leverages SSL/TLS for key exchange, allowing it to encapsulate a wide range of network traffic securely. This capability makes it suitable for site-to-site and client-to-server VPN connections.

OpenVPN typically listens on port 1194 by default but can be configured to use any port, aiding in circumventing restrictive firewalls or network policies. It supports multiple authentication methods, including certificates, username/password, or two-factor authentication, ensuring a customizable security setup. Furthermore, OpenVPN is cross-platform, running on Windows, Linux, macOS, and various embedded systems, which enhances its versatility.

Its highly configurable nature allows administrators to tailor encryption standards, LZO or LZ4 compression, and routing options to fit organizational or personal needs. This flexibility, combined with community and commercial support, contributes to OpenVPN’s widespread adoption for secure remote access, cloud connectivity, and secure site interlinks.
