[Openstack] Need help setting up routing to my instances

Update.  I've done a fresh install and am successfully running instances 
on my compute host, but, while I can connect out of my instances just 
fine, I can't get into them from any host but my compute host.

I thought that RDO was going to set me up so that each compute host 
handled the routing directly, but it appears that all of my instance's 
traffic is routing through a bridge to my control host.

My compute and control hosts are on a 192.168.0.0/16 network and are 
using 192.168.20.0/24 for the instances.

How do I get traffic routing into my instance hosts on 192.168.20.0/24 
on each compute host?  (I only have one now, but will be deploying 2 
more once I have OpenStack set up.
