OpenVPN config files (. ovpn) offer an easy way to configure #OpenVPN on your computer to work with our servers. These files contain the correct cipher types, #Certificate Authority, Certificate, and Private Keys. You can use these files on Mac, Linux, #Windows, Android, and iOS.

By default the OpenVPN Access Server comes configured with OpenVPN daemons that listen on port 1194 UDP, and OpenVPN daemons that listen on port 443 TCP. While the best connection for an OpenVPN #tunnel is via the #UDP port, we implement TCP 443 as a fallback method.
