Snow Leopard firewall in stealth mode, but responding to ping requests?

    I've just tried running the security test on the Shields Up! site, and I note that even though my firewall is in stealth mode (and Shields Up! reported that all the ports it probed were stealthed), it failed the test because it replied to an ICMP ping request - and yet the Snow Leopard firewall specifically states that when it's in stealth mode, it won't respond to such requests.

    Is this something I need to worry about?

    It's possible that your internet router/gateway is the device replying, not the mac itself.

    Yes, you'll want to log onto your router's configuration pages and make sure all non-essential incoming ports are blocked, and it might have an option to stealth its ports as well.
