<br>
<font size="2" face="sans-serif">So your DHCP agent is not working as expected. Check if the agent is configured properly and running. The DHCP agent should assign the IP address from private tenant network to the VM. Only then you can connect to it through floating IP.</font><br>

Hi Akash,<br>
<br>
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?<br>
I also have a installation guide document that I followed, if you want it for reference.<br>

Hi,<br>
<br>
I have deployed Kilo using Packstack on CentOS , but I am having troubles accessing the VM's that I spawn , through the public IP's that they are assigned to them. <br>
<br>
I created my network as follows:</font><font size="2" face="Arial"><b><br>

<font size="2" face="Arial"><br>

Also I made changes in the ifcfg-br-ex file and ifcfg-<my network> file in </font><font size="2" face="Arial"><b>/etc/sysconfig/network-scripts.</b></font><font size="2" face="Arial"><br>
<br>

There is also a proxy in the network and so for that, I installed by "</font><font size="2" face="Arial"><b>packstack --allinone --provision-demo=n --provision-all-in-one-ovs-bridge=n</b></font><font size="2" face="Arial">".<br>

Could someone suggest me a reason as to why i might be facing issues or probably where I can look to debug this issue.<br>
