  <p>I've seen the multi-nic feature in OpenStack, but that seems to link OpenStack Networks together, not physical NICs. Another option I've looked into is using the routing tables, but I don't know if this is possible/best practice.</p>

  There are many layers to that question :
  
  * How did you deploy Openstack? This will heavily influence the flexibility you have the expose API access.
  * I assume you mean the Openstack API (nova,neutron,keystone,cinder) itself?
  
  Usually, the core API services are listening on your internal networks only.
