demo-router not pingable from external network (a promiscuous mode problem)
I have followed the Icehouse doc "OpenStack Installation Guide(three-node)". My environment is same as the doc except IP and nodes that are builded as VM using libvirt(qemu/KVM) in CentOS 6.5 as below
I can not ping floating IP of demo-router from external node in this stage -> http://docs.openstack.org/icehouse/in...
I think this problem is related to promiscuous mode. Because, I can capture "ARP request" and "ICMP echo request" in ① and ② interfaces in the picture above, but in ③, I can only capture "ARP request" packets.
why are "ICMP echo request"s blocked after ②.
I have set..
- ①, ② and ③ are set into promiscuous mode using "ip link set [INTERFACE_NAME] promisc on"
- ICMP and TCP are enabled in "nova secgroup"
- MAC addresses of both side are updated on each ARP table.
I have found a post in same situation I am in -> https://ask.openstack.org/en/question... but I don't understand a way of solution in that post
Any hints would be much appreciated!.

hi SGPJ, I could not find something to solve this problem in the post. I am looking for a way to get IP packets as well as ARP packets on "eth1" in VM3 in the picture on my post.
Hi Jazzsir, I have the same issue with Juno and Kilo, not sure if you have resolved the problem or not, if yes, would you please share your solution? Many thanks in advance!
I guess this problem was related to virt_type http://docs.openstack.org/juno/config.... But I haven't tried..
