I am running virtual box on my macbook pro with Centos 6.5 as the guest. I've setup Vbox with a bridged connection with my wireless card.

I installed openstack allinone using packstack with no issues. (Icehouse) I created an answers file and just made sure CONFIG_PROVISION_ALL_IN_ONE_OVS_BRIDGE=n was default. (Which it was).

I am running vbox on my home network so my IP's look like 192.168.1.x .

I set up openstack for external networking because I want to be able to connect from my laptop. Currently I can only connect from my guest centos server but not my MAC Book.
I want to be able to connect from my mac book (or any of my other servers on my home network).
Most of my networking was based on .

https://openstack.redhat.com/Neutron_... . I found many similar things online which helped as well.

I set the following in the /etc/neutron/plugin.ini (Not sure why?)

network_vlan_ranges = physnet1
bridge_mappings = physnet1:br-ex

My configurations on my centos guest server are
