Public bug reported:

When using DVR, if traffic is sent to the fixed IP of an instance using
the FIP gateway as the next-hop it is dropped by the FIP gateway.  The
FIP gateway should act as a generic gateway to both fixed IP's and
floating IP's.  This is an enabler for north-south DVR without using
floating IP's.  I believe the FIP gateway just needs routes to point to
fixed IP's the appropriate qrouter.  The address scope of the external
network and tenant networks should be the same if direct routing to the
fixed IP is to be supported.  Once this is fixed, BGP can announce the
FIP gateway IP as the next-hop for each fixed IP host route accessible
on the given compute node.
