Hi,


We are trying to set up a OpenStack based private cloud. We have 2 networks
one a dmz network with little or no restrictions and
the other a corporate network with all the corporate access policies in
place.

The goal of setting up this private cloud is to ensure that any vms that
come up in the OpenStack cloud should have I.P. Addresses assigned
either in the dmz or corporate network or both depending on the project
requirement.

We currently have a 4 server setup, every server in the setup has 4 nic
cards each. We are planning to have a network,controller,compute and
storage node with future plans of adding HA to the setup.

We have set up a network controller node with 4 nics.  We are planning to
map the first nic to the dmz network, the second nic to the corporate
network, the third and
fourth nic to the management and data network respectively.

Currently we are trying to bridge map each of these 4 interfaces on the
network controller to the dmz, corporate, data and management networks
respectively.

I would like to get pointers on how to go about with this approach or if
the community can suggest any better solutions than bridge mappings to
achieve our objective.

Regards,
