LTSP-pnp + 2 NIC setup + Network Manager but no NAT

[David Groos]

Couldn't get it to work. Did the following:

   1. sudo mkdir /etc/network/if-up.d/sch-scripts
   2. cd /etc/network/if-up.d/sch-scripts
   3. sudo wget
   http://bazaar.launchpad.net/~ts.sch.gr/sch-scripts/trunk/download/head:/schscripts.ifup-20120905033826-9obnmtt73i3weito-1/sch-scripts.if-up
   4. sudo chmod +x sch-scripts.if-up
   5. sudo reboot

--Restarted a client, firefox couldn't access the internet.

--Uncommented "dhcp-range=192.168.3.0,proxy" in
"/etc/dnsmasq.d/ltsp-server-dnsmasq.conf" in case this was an issue.
restarted server and then client and still firefox couldn't access the
internet.

--Rebuilt image with: sudo ltsp-update-image --cleanup / and then restarted
client and still firefox couldn't access the internet.

--I poked around the server logs but couldn't find anything interesting.
Name for wiki page?:
https://help.ubuntu.com/community/UbuntuLTSP/NATwithNetworkManager

Any ideas?
Thanks!
