VM not accessible from external host through public IP and it cannot ping external gateway also
Hello,
I am using dell Poweredge server with Ubuntu 14.04.5 with OpenStack Newton release (single node installation). However whenever I create a VM on Private NW and assign a Floating IP to it (for test, created a VM with Cirros image also), I am not able to ping the VM from Dell server using the Public IP. Also from inside the VM, I am not able to ping the Public IP gateway or the Dell server. The installation is done using Devstack. Though I am able to ssh into the VM using ip netns exec dhcp of the Public network.
The LAB LAN IP is of the series 10.10.15.0/24 (used as public IP range). The Dell server has IP 10.10.15.203. Gateway is 10.10.15.2
The Private NW is- 172.16.0.0/24.
Any Help would be highly appreciated.
Ifconfig of the Dell server is -
