Run the installation file and grant necessary permissions when prompted by UAC. The installation process typically takes 2-3 minutes on modern Windows systems.
Launch OpenConnect GUI and add a new connection profile with your VPN server details. Set up authentication credentials, certificates, or token-based login as per your network requirements.
Initiate the connection process and authenticate with your credentials when prompted. Monitor connection status through the system tray icon and verify successful network access.
Verify server address accuracy and network connectivity before attempting connection. Confirm certificate validity and authentication credentials with your network administrator.
