[Openstack] Instances can't access eachother via external (floating) ips?

Hi,
I have instances running in Openstack using FlatDHCP networking mode.
Each one has an IP address in the internal subnet (192.168.22.x) and a
floating IP from the external subnet (192.168.0.x).
I've found that from one instance, I cannot connect to another instance
(or, in fact, even the same instance) via the external floating address
(I have some monitoring tools that attempt to do this to verify that a
server is running). Connections from external computers work fine.
My best guess is that there is an issue with the NAT on my nova-network
node not allowing loopback connections. Is this intentional, or a bug?
Is there a workaround available?
For reference, I'm currently using OpenStack from the
'latest-milestone-test' OpenStack PPA on Ubuntu 12.04 Precise.
