Hi David,

Not sure if you've checked this yet but the config file that (at least used
to) assign the HW address of the NIC to the port is located in:
/etc/udev/rules.d/70-persistent-net.rules.  If it is strange (happened in
my case when cloning a 'golden server' you delete this file and will be
re-generated upon restart with the accurate info.  Then, perhaps by
commenting out the NIC you don't want in this config file and restarting
the server, the NIC will disappear?

What I would recommend doing is working through this wiki
page<https://help.ubuntu.com/community/UbuntuLTSP/ThinClientHowtoNAT/>as
it has received much loving care to be REALLY helpful when working to
get internet working on thin client networks.  I've used that page to
troubleshoot more than 1 time...

Good luck,
David G
