openfortivpn is a command-line SSL VPN client for connecting to Fortinet FortiGate gateways without relying on proprietary GUIs. It negotiates the SSL/TLS tunnel, authenticates with credentials (and commonly with two-factor methods), then brings up a secure point-to-point interface and installs routes and DNS settings. The tool aims to be minimal and dependable: a single binary with an INI-style config file, systemd compatibility, and clear runtime diagnostics. It handles details like MTU tuning, split tunneling via pushed routes, and reconnect logic to keep the session stable. Because it works with the standard tun interface, it integrates smoothly with common Linux networking stacks and pairs well with desktop frontends such as NetworkManager plugins. For admins and developers, it’s a scriptable, cross-platform-friendly alternative that makes FortiGate access reliable on servers and developer workstations alike.
