Please describe the way you are getting IP addresses?  Is there a DHCP
server out there somewhere?  Are you setting them static?  What tool did
you use to configure the network?  What is the output of

  ifconfig

and

  route

on each node at this time?  People here can probably help you, but
you'll have to give details of EXACTLY what your setup is, as there are
a thousand ways to set up a network incorrectly.
