    What do these two things mean? Public_UPNP_C3 And ICMP_echo_req ?
    my dad's pc is the 192.168.1.5 And it also sends near nonstop audit requests to my computer for some reason. Could his computer be hacked or something? Any help will be much appreciated :)

    According to a post on netgear

    for the Public_UPNP_C3 events

    Service blocked looks as if you have ICMP ping response disabled, just saying it's attempted to ping your IP and the router didn't respond afaik.

    Most SOHO routers contain a Firewall. It's Firewall's job to stop devices out on the Internet connecting to devices on your LAN.

    All the stuff about address that are not 192.168.X.X is the Firewall doing it's job.

    It's a bit like a telephone system you get in some commercial premises that has been configured to allow outgoing calls but block all the incoming ones.

    Since we have several computers in our home I did a little investigating. All of our computer except my Samsung windows 8 do not log this echo ping thing. I accessed my modem from another computer and surfed all of the computers. Only when I surfed with mine did this show up so my question is....is it a windows 8 issue or my Samsung pc issue? I use webroot for antivirus and spybot. I scan it everyday.
