Internet TCP port 1194 is primarily used by OpenVPN, an open-source software application that implements virtual private network (VPN) techniques. This software creates secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities. It uses a custom security protocol that utilizes SSL/TLS for key exchange. Therefore, port 1194 is typically open on the firewall to allow VPN connections.
