RE: Grumble...

Final piece to the puzzle.  When I put up a sniffer, the AS/400 doesn't even
make a peep on the network during the ping.  When I ping internally, I see
two ARP broadcast packets from what I assume is my AS/400, followed by a
response from what I assume is my router.  After that, there are a bunch of
ICMP echos and replies.  When I ping an unconfigured address in the net,
there are a whole bunch of ARP broadcasts, but of course no replies.  And
when I ping an address NOT in the subnet, there isn't even a peep on the
ether - not even an ARP broadcast.

So how about THEM apples, eh?
