SOS!!cannot ping br-ex in networknode with havana
I have 3 nodes with neutron gre tunnelling, and I can assigned private and floating ip to instances. the only question is, the instance cannot get to internet.
1) I can ping the qg-xxxxx form instance, but failed form networknode, even in namespace qrouter-xxxxx.
2) I can ping the br-ex from networknode, but failed form instance.
both said ' Destination Host Unreachable '.
here is detail:

the physic gateway_IP: 172.31.9.1, and I set it as my ext_net gateway
I think this may relate to namespace or br-ex(bridge and qg-xxx is not connect or something), anyone knows how to solve this problem ?
Thanks
