I have installed Devstack Juno on my ubuntu 14.04 VM.
I have only one NIC its in bridged mode. Its IP is
I want to use same subnet IP's as my floating IP's so that I can access
Devstack VM's from outside network, like my host machine.

When I installed Devstack Juno it has pre-allocated with
subnet, I can create VM's and can assign floating IPs and can
ping all these VM's from the host.

Afte adding

*sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE*

I can access outside network from VM's, but I can't access VM's from
outside network as they are NATtted. I tried giving as my
floating IP's but still VM's are not pingable

Can any one please share the localrc and help me to use my subnet as my floating IP's so that I have outside connectivity.
