Configure the client by entering your organization’s VPN server address and credentials. Specify authentication method, certificates, and any custom connection parameters required.
Initiate the connection process and authenticate with your credentials when prompted. Monitor connection status through the system tray icon and verify successful network access.
Check firewall settings and ensure required ports are open for VPN traffic. Confirm certificate validity and authentication credentials with your network administrator.
