I have been following along IceHouse installation guide for a multi-node setup. I have reached the point the the tennat gateway router should be pingable from the external netwrok however I can't seem to access it.

Here is some trouble shooting information of the network node (external IPs are obscured but correct):

[root@network ~]# ip a

The problem has been identified and resolved as a result of a stupid problem:

Iptables was blocking qpidd....

sigh..

The above configuration works now.

Thank you very much for identifying the security issues however.

        1. neutron-server:                         inactive  (disabled on boot)
        2. [root@network ~]# nova secgroup-list-rules default

        This are  a serious mistakes
        Your Neutron Server is not alive, security rools not implemented

    Security rules enabled looks like
    [root@icehouse1 ~(keystone_admin)]# nova secgroup-list-rules default

neutron-server is running on the controller node:

[root@controller ~]# openstack-status

openstack-nova-cert:                    active

qpidd:                                  active

And I have implemented the correct security rules:

[root@network ~]# nova secgroup-list-rules default
+-------------+-----------+---------+-----------+--------------+
| IP Protocol | From Port | To Port | IP Range  | Source Group |
+-------------+-----------+---------+-----------+--------------+

| icmp        | -1        | -1      | 0.0.0.0/0 |              |
|             |           |         |           | default      |
|             |           |         |           | default      |

Mistakes again :-
neutron-dhcp-agent: inactive (disabled on boot)
neutron-l3-agent: inactive (disabled on boot)
neutron-metadata-agent: inactive (disabled on boot)

dbaxps gravatar imagedbaxps ( 2014-06-22 21:44:51 -0500 )edit

Active on the network node (as per the guide):

[root@network ~]# openstack-status 
== neutron services ==
neutron-server:                         inactive  (disabled on boot)
neutron-dhcp-agent:                     active
