<font size="3" face="serif">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?</font><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:<br>
</font><font size="2" face="Arial"><b><br>

<ul style="padding-left:36pt"><font size="2" face="sans-serif">1. </font><font size="2" face="Arial">a. neutron router-gateway-clear router1 (neutron router-gateway-list)<br>

<font size="2" face="Arial"><br>
c. neutron router-gateway-set router1 public</font></ul>
<font size="3" face="serif"><br>
</font><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="3" face="serif"><br>
</font><font size="2" face="Arial"><br>
The Changes were as follows:</font><font size="3" face="serif"><br>

<p><font size="3" face="serif"><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">".</font><font size="3" face="serif"><br>
</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.</font><font size="3" face="serif"><br>
