[Openstack] External network Issues

Hi Akash,

I made the changes you pointed out, but it doesn't seem to make any
difference. I am in the same network as the server but still not able to
ping or ssh to the vm. I double checked my networking rules and have
configured tcp and icmp properly. Don't really know where this might be
breaking. Is there anything else I can do to debug this issue?
I also have a installation guide document that I followed, if you want it
for reference.
