    Certainly interesting that some work and some don't.
    Almost ALL routers give you a control to enable/disable "Respond to ping from the Internet" side. It is thought that not responding is a better choice as ping is used to find systems that can then be further probed for implanting a virus (there are other techniques too however).

    I've never seen a ping from that LAN side be configurable NOR fail to work either unless there's a real Source connection issue.

    Also never possessed a Cisco router, so can't be sure what does/doesn't work here.

    BUT; is this a real problem that demos some pc issues or just oh my, how interesting ..... ?
