Subject: Why a host not ping-able?

Hi, list

I am not sure this has something with kernel.  But the system I just
generated cannot be reached from ping.  It can ping outside, but if I
ping it from outside, I just get "Destination Host Unreachable".

I think there is not firewall in between, and the two host in the test
are in the same ethernet sub network.  Is that possible the strange
behavior caused by somehow misconfigured kernel?

I can't go back to yesterday - because I was a different person then.
