  4. Enter a name and description for the configuration
  5. In the Firewall Action section, select Don't Modify
  6. In the Firewall Configuration section, click Customize
  7. In the Customize Firewall Ports window, in the Add to Selected Ports section, enter the following information:
    • Port Name: VNC Port
    • Port: 5900
    • Protocol: TCP
  8. Click Add
  9. Close the Customize Firewall Ports window
  10. In the Firewall Configuration section, enter the following information:
