I did all that the doc tells me to do, which includes setting up a bridge in the network node. Just like http://docs.openstack.org/grizzly/basic-install/apt/content/basic-install_network.html#basic-install_network-services I did the Procedure 2.2-4 and 2.2-5.

Did you create br-ex bridge and associated the external as a port to it?

Everything works well except that the VM instances cannot connect to outside. Among VM instances they can connect to each other. Attached the network diagram: [cid:image001.png at 01CEBBB7.23003AF0] In VM, it can ping the demo-router address 10.5.5.1 (internal) and 10.200.29.33 (external). But it cannot ping out the other external addresses. Both the public and demo-net network work normally: Project Network Name Subnets Associated Shared Status Admin State admin public public-subnet 10.200.29.0/24<http://10.200.29.0/24> No Active Up demo demo-net demo-net-subnet 10.5.5.0/24<http://10.5.5.0/24> No Active Up But the port where the demo router is DOWN (bd10e227) 10.200.29.33 network:router_gateway DOWN UP The port info: Port ________________________________ Name None ID bd10e227-8f83-4804-9f68-a0e643e451e5 Network ID d415febb-b387-40e0-9416-32c1b19d5b46<http://10.200.29.31/horizon/project/networks/d415febb-b387-40e0-9416-32c1b19d5b46/detail> Project ID - Fixed IP IP address: 10.200.29.33, Subnet ID 6781dfdc-508b-46c3-89ce-5624f95448d0 Mac Address fa:16:3e:e2:b2:b3 Status DOWN Admin State UP Attached Device Device Owner: network:router_gateway Device ID: 5d43330d-c0ee-4bd5-a76f-b15daad1df2e Could anyone please give me some clues to solve this problem?
