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 image description

I can not ping floating IP of demo-router from external node in this stage -> http://docs.openstack.org/icehouse/install-guide/install/yum/content/neutron_initial-networks-verify.html

I think this problem is related to promiscous mode. Because, I can capture "ARP" and "ICMP echo request" in ① and ② interfaces but in ③, I can only capture "ARP" packets. (①, ② and ③ are set into promiscuous mode using "ip link set [INTERFACE_NAME] promisc on")

I looked for problem solving method -> https://ask.openstack.org/en/question/7705/havana-neutron-networking-cant-escape-namespace/

but I don't understand..

  1. ①, ② and ③ are set into promiscuous mode using "ip link set [INTERFACE_NAME] promisc on")on"
  2. I checked "nova secgroup" - ICMP and TCP enable
  3. MAC addresses of both side are updated on each ARP table.

I don't know why "ICMP echo request"s are blocked after ②.

why are "ICMP echo request"s blocked after ②.

I have set..

  1. ①, ② and ③ are set into promiscuous mode using "ip link set [INTERFACE_NAME] promisc on"
  2. I checked ICMP and TCP are enabled in "nova secgroup" - ICMP and TCP are enabledsecgroup"
  3. MAC addresses of both side are updated on each ARP table.
