one possible reason can be that your VM didn't get IP address from its DHCP server. Can you check your VM instance log (You can check it from dashboard) and see whether its sending the DHCP request for IP and getting any response from it

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.
