Open Stack

Hi,

I set up openstack environment on Ubuntu 12.0.4 with 3 nodes according to the starter guide on docs.openstack.org. 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:

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      No                  Active              Up
demo    demo-net                  demo-net-subnet 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:

Could anyone please give me some clues to solve this problem?
