    I looked up my ip on www.grc.com and I pinged it. It responded. I though when a firewall is in stealth mode as mine is it will not respond at all. Or am I confusing it with something else? It does not respond to the www.grc.com test and is said to be stealthed

    Hope this is in the right forum

    Hello,
    Did you ping it locally? Because in that case, you are the source of the packet, so no reason why not to accept it ... Check your firewall rules / logs.

    Check your FW configuration to ensure you are not permitting ICMP Echo.

    In ZA the settings are at Firewall/Main/Custom, as per screenshot.

    Hello,
    You pinged yourself from the same computer - that's local.

    To select the pop-up you just left click it to ensure it is highlighted. Then press Alt print screen to copy it to the clipboard. Then you paste it into paint.

    Hello david banner,

    As mentioned by Mrkvonic, you will receive reply from local ping with whatever firewall you use. When pinging yourself (your own PC) the packet(ping) will not leave the PC, it will simply reply to itself.

    The shields up site (http://www.grc.com/) will ping remotely, so will show if your PC will actually reply to a ping from other remote PC`s.

    Hello,
    Although some firewalls can be configured to drop ping even for localhost - for instance, iptables. I'm not sure if there are Windows firewalls that can be configured to do this ...

    I hope you have peace of mind on this now?

    Hi Mrkvonic,
    Pings to own IP will not go through local host, they are processed before this. (you can set up local sniffer to verify)
