Title:
  Inconsistent connectivity between instances with floating IPs

Status in OpenStack Compute (Nova):
  Fix Released
Status in OpenStack Compute (nova) grizzly series:
  Fix Committed

Bug description:
  Communication between instances on the same fixed network using
  assigned floating IP addresses does not behave in a consistent
  fashion. In all-in-one and (possibly) multi-host deployments, creating
  connections using floating IPs appear to work (at least within the
  confines of the security groups). However, with standalone compute
  nodes, instances that are on the same compute node cannot successfully
  create a connection. Routing and matching endpoints seem to be at the
  core of this issue.
