[Openstack] instances without a floating ip address

That is what I thought but it does not seem to be working this way. How would I check our snat namespace and what specifically should I be looking for? My apologies but am very new to openstack.

But, there should be a ip from the external network that gets assigned to SNAT namespace on network node, this effectively will let all vm's (without floating ip) access external resources.

>> Need some clarification regarding routing for instances without a floating ip address. Basically we have instances connected to a priv network that is also connected to our external network and our security group allows all egress traffic. However, we can't seem to get to any resource on our external network till a floating ip address is assigned. Once we assign a floating ip address we can get out. Is that by design or is there something wrong with our configuration?
