Comment 4 for bug 1794142

I will verify this issue on the Cisco set up tomorrow. I have seen this issue in the past using VM's and typically changing the the values of INTERNAL_NET and EXTERNAL_NET in /usr/sbin/startnat.sh has worked to get the from the SUT, to the outside world, via the MAAS VM. Typically I have had to make this change and re-run the script after power interruptions or rebooting the MAAS VM.
