</div>
<div>I have a problem that a launched instance from openstack cannot connect to SSH or PING </div>

<ol>
<li>I did install RDO (allinone host) using the bellow steps <a href="https://openstack.redhat.com/Quickstart" target="_blank">https://openstack.redhat.com/Quickstart</a></li><li>Then I have used the following steps for floating IP <a href="https://openstack.redhat.com/Floating_IP_range" style="font-family:Consolas" target="_blank">https://openstack.redhat.com/Floating_IP_range</a>.</li></ol>
<div>My situtation is as follows. </div>
<div style="font-family:Consolas">* Floating IP address assignment: </div>
<div style="font-family:Consolas">I have assigned a floating IP , I did follow this steps.</div>

<div style="font-family:Consolas">* DHCP configuration: Yes, DHCP configuration is set and Neutron hearing and responding to DHCP</div>
<div style="font-family:Consolas">requests and the instance is getting IP from 10.48.146.113 (next hop) however I cannot ping/ssh to that IP address (ICMP/SSH is added allowed</div>
