Hi All,

I have a setup where controller/network node is running on one server and i
have another server as a compute node. I am able to launch the VM and VM
gets its private IP from its respective DHCP server as well. VM is
connected to its private network. Private network is attached to the router
and external network is set as a gateway for the router. I am able to
associate floating ip to the VM as well.

But when i ping this floating ip from internet, i am not able to ping.
Although i am able to ping the gateway ip of the router. I checked the ARP
entry for the floating ip, and its successfully resolving the arp for this
floating ip.

I can see this address in the router name space as well.

# ip netns exec qrouter-3d7dfce4-c19a-4448-b276-1631690a403c ip addr

    inet 9.126.108.126/24 brd 9.126.108.255 scope global qg-d75a619f-ac

    inet6 fe80::f816:3eff:fe2e:c64b/64 scope link
       valid_lft forever preferred_lft forever


So i can ping 9.126.108.126 but i am not able to ping 9.126.108.127. Also
both of these IP actually resolves to the same MAC address, is it expected
? I added rules in the default security group to allow TCP/UDP/ICMP traffic.

Please let me know if anybody has any clue on whats going on here , and how
can i further debug it. Please let me know if you need any other details.
