Ping duplicates

["Erik Mathisen" <mathisen cleveland crosswinds net>]

Hello,
	I  am working on setting up my interneet conneection on my home network.  I
have one machine on a cable modem that is my gateway.  The machine that I am
trying to learn linux on has a prive IP address of 192.168.0.13.  The
gateway to the machine with the cable modem is 192.168.0.1 on the private
network and then I have program (its a Nt machine) to route me to the
internet.  Ok now here is the question : i tried to test my internet
conneection by pinging the gateways real IP and not the private one, it
works but I got duplicates.  Here is what i got:

Any suggestions?  Ohh yeah I am using ehternet cards for the network and
they all appear to be working.
