 Hi,

  We are running OpenStack Folsom on CentOS 6.4.
Quantum-linuxbridge-agent is used.
By default, the Quantum node has the following entries in its /etc/sysconfig/iptables file.

-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited

 With those two lines, VM cannot get IP address from the DHCP server running on the Quantum node.
More specifically, the first line prevents a VM from getting IP address from DHCP server.
The second line prevents a VM from talking to other VMs and external worlds.
Is there a better way to make the Quantum network work well
than just commenting them out?

 I'll appreciate your help.

 David
