Open Stack

Оk, now you need to see if traffic get though networking node.

Set up ping to you instance from something outside.

1. Check if you see icmp packets on eth1. (tcpdump -ni eth eth1)
2. Sneak to router namespace on networking node (ip net exec 
(qrouter_here) /bin/bash)
3. Check if you see them on interfaces inside namespace
4. Check if you see them on gre-interface of networking node 
(gre-wrapped, if you using gre tunnels)
5. Check if you see them on gre-interface of compute node
6. Check if you see them on instance interface

Kinda default checklist to check every interface packet passing between 
'outside' and instance.
