Obtain the Windows-compatible version from the project’s official download page. Look for the MSI or executable installer package for straightforward setup.
Launch the downloaded installer with administrator privileges for proper system access. The installation process typically takes 2-3 minutes on modern Windows systems.
Configure the client by entering your organization’s VPN server address and openconnect credentials. Specify authentication method, certificates, and any custom connection parameters required.
Select your configured connection profile and click connect to establish the VPN tunnel. Confirm successful connection through status indicators and test network accessibility.
Check firewall settings and ensure required ports are open for VPN traffic. Validate that your user account has proper VPN access permissions.
Ensure system clock is synchronized and certificates haven’t expired. Check for self-signed certificates that may require manual acceptance.
Note: For organization-specific configurations, consult your IT department for exact connection parameters. Some networks require additional security software or specific configuration tweaks.
