ICMP request dropped
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
Can you do an ip route and check if you are able to see the default gateway from inside the server?
