Hi,
I've installed openstack using quantum by the guide 
https://github.com/mseknibilel/OpenStack-Folsom-Install-guide/blob/master/OpenStack_Folsom_Install_Guide_WebVersion.rst
everything works fine, but I can't ping vm from the outside world, neither from the network node.The following is some of my configration.
1) root@networknode:/etc# ip netns 
qrouter-8f5f3c17-a00e-4382-a403-181dfbb9d189
qdhcp-e58739ff-16dc-4289-8110-242f7818d314
2) qrouter and qdhcp server is up
root@networknode:/etc# ip netns exec qrouter-8f5f3c17-a00e-4382-a403-181dfbb9d189 ifconfig
