With the move to Neutron, a certain number of things which should be
done automatically are not done:

1) Set up an internal network & subnet for guests (I believe this is
automatically done by Packstack now)
2) Create a default router and attach the internal subnet to it
3) (not sure if this can be done automatically, or whether it needs to
be a post-install config step) Attach the external network as the
gateway for the router, and create some floating IP addresses outside
any DHCP range on the public network to associate with newly created

I think this is network namespace related: routing from an int to ext
network isn't automatically done, you either need to create an L3 router
and connect the networks to it, and/or ensure that your local IP address
is routing directly to the instance via the router.
