Hi, I installed Openstack Newton in two ubuntu 16.04 setup. I created the openvswitch based provider network. VM is instantiated. From gateway I can login to VM. From VM I tried to ping gateway. It is not working.

when I ping from VM, In my tap interface sudo tcpdump -i tapbfc1dccf-70 I got ICMP request message.

when I do sudo tcpdump -i qvbbfc1dccf-70 Nothing coming. ARP request and ARP reply goes well. It is only enabled default security policy with ssh and icmp. My question why VM cant ping to gateway. I need to modify something linux bridge for iptables.

Thanks for your explanation.

Best regards Sothy
