Hi there,

I have been using the following resources for configuring openstack:

https://github.com/mseknibilel/OpenStack-Folsom-Install-guide/blob/master/OpenStack_Folsom_Install_Guide_WebVersion.rst (https://github.com/mseknibilel/OpenSt...) http://docs.openstack.org/trunk/openstack-network/admin/content/install_ubuntu.html (http://docs.openstack.org/trunk/opens...)

Here are the results in of my interfaces as it stands (ifconfig -a):

From the output of ifconfig I see that you have the ip addresses on the interfaces these should be on the bridges. For example,

eth3 Link encap:Ethernet HWaddr d4:85:64:30:40:14 inet addr:192.168.65.64 Bcast:192.168.255.255 Mask:255.255.0.0 Should be on: br-eth3 Link encap:Ethernet HWaddr d4:85:64:30:40:14 BROADCAST MULTICAST MTU:1500 Metric:1

If you run the following that should help correct this:

ifconfig eth3 0.0.0.0; ifconfig br-eth3 192.168.65.64/16; (Same with eth1)

I'm not sure if this is what is causing your issue but this is definitely an issue... let us know if you still have the same issue after making those changes.

I set eth1 and eth3 to 0.0.0.0 and then set the IPs on br-eth3 and br-ex as per your instructions and now I can ping ips on the respective networks again.

Thank you! Edwin
