Hello Justin,

  Actually, using pump as the client and having a properly setup DHCP
  server, the DNS settings are passed on and picked up correctly. I
  have this running on serveral YellowDog systems as well as RedHat
  and HardHat systems. If the server isn't setup to pass on gateway
  and DNS settings, then the client won't set them up properly when it
  gets it's IP. Might want to make sure your dhcpd.conf file is setup
  correctly on the server.
