Creating a network without NAT in essex
We're looking for a way to configure OpenStack so that it assigns ip addresses from a given subnet of our internal network without any NAT rules in place.
Currently we use a similar setup as outlined here:

It essentially disables nova-network, and allows an external DHCP server to assign ip addresses to the instances. This works, but it breaks major functionality within OpenStack (like parts of the api, and metadata) and it makes using the system a pain.
Is a NAT free network possible under essex?
