Hi Dag,

Thanks for the reply. I am trying to use Shapeblue CCS (Container as a
Service) with ACS, but for that Isolated networks are required which are
only available in Advanced Zone. Further, I want to explore Cloudstack
further and am also aiming to test and configure other advanced features
such as load balancing and auto scaling without netscaler device. For that
I badly need Advanced Zone networking (especially isolated networks
offerings). I just want to know if Advanced Zone can succesfully function
with two networks, one physcial NIC and no VLAN tagging.

Thanks,
Parth Patel
