No Internet with Network and LTSP working

Installed new copy of Edubuntu 14.04 LTS, with LTSP installed out the gate. I have 2 network cards as advised.

On boot up it tells me there is a "Failure to download extra data files" for the flashplugin-installer as there is no internet connection.

eth0 is facing out to the web, and connected on 192.168.0.14 mask of 255.255.255.0
eth1 is for LTSP and connected as 192.168.0.1 mask of 255.255.255.0

I would think that this might be the problem as two nic cards have the same ip address. However everything I try to do to change the IP addresses never seems to be enough.

-----------------------------
etc/network/interfaces

#interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
auto eth1 inet static
  address 192.168.0.1
  netmask 255.255.255.0
-----------------------------

I would think to add a auto eth0 and move the eth1 to 192.168.1.1 but this does not seem to work.

etc/ltsp/dhcpd.conf

authoritative;
subnet 192.168.0.0 netmask 255.255.255.0 {
  range 192.168.0.20 192.168.0.250;
  option domain-name "example.com";
  option domain-name-servers 192.168.0.1;
  option broadcast-address 192.168.0.255;
  option routers 192.168.0.1;
  option subnet-mask 255.255.255.0;
  option root-path "/opt/ltsp/i386";
  if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {
        filename "/ltsp/i386/pxelinux.0";
  } else {
        filename "/ltsp/i386/nbi.img";
  }
}
-----------------------------

Again if moving eth1 to 192.168.one.xxx I would think all the 192.168.0 should be replaced with 192.168.1

Alas I am missing something as when I look at the GUI network drop down menu I see "Wired connection 1" is connected on eth0, but eth1 will say "device not managed" or "disconnected", varies with what I have tried.

Currently I can connect with a PXE Thin Client and get in, but I have no Internet Access that should be coming from Eth0 the only thing that was a connection.

I pulled my wifi card and have been tring to make this all work with wired connections, as is seems the wireless trumps all other connections in Umbuntu.

I dabble with Linux, but my background is Windows.

Any ideas on how to get this to work, been reading forums for 2 days. Currently I have reinstalled the OS for the 4th time, cause I keep messing up things looking for a solution.
