    It might also be fallout from someone spoofing your addresses to probe or
    DoS the "BAD.GUY.NET.NODE" network.. You might want to capture some of
    those packets with a sniffer and decode the payload of the icmp error.
    That will give you a clue as to what packet caused the remote end to emit
    an icmp 3/1 host unreachable..
