FAQ: How can I enable ping with Windows Firewall?

FAQ M8

It is a requirement that CUDN-connected computers must support the ICMP Echo (ping) function. The Windows Firewall may not respond to such incoming echo requests. If you intend to use Windows Firewall on the CUDN you must enable ping.

NOTE: Please see "The Home User Guide to PC Security" and "What should I do when I connect my personal Windows computer to the network?" for further information on PC security.

Windows XP SP2 or SP3

  1. Open the Control Panel (from the Start menu - choose Control Panel or Settings and then Control Panel).
  2. Open Windows Firewall (click Network and Internet Connections then Windows Firewall or double-click Windows Firewall.
  3. On the General tab of the Windows Firewall dialogue box, make sure that the On (recommended) radio button is selected.
    [You do not need to use two firewalls. Doing so may lead to confusion. If you intend to use Windows Firewall but have another firewall installed (such as ZoneAlarm) you should uninstall it - preferably before installing Windows XP SP2. If you decide you prefer an alternative to the Windows Firewall you can always reinstall it later].
  4. Click the Advanced tab.
  5. In the ICMP box click the Settings... button.
  6. Tick the Allow incoming echo request box.
  7. Click on OK and then OK again.
  8. Close the Control Panel.
