Neutron duplicating inbound traffic

Hi all!

I upgraded to IceHouse from Havana, and everything is working with the exception that Neutron seems to be duplicating inbound traffic, which causes a massive snarl-up for anything more complex than a ping.

A tcpdump of a single PING request to my instance looks like:

18:12:53.908605 IP xxx.xxx.xxx.xxx > 10.0.0.41: ICMP echo request, id 26889, seq 55009, length 64
18:12:53.908612 IP xxx.xxx.xxx.xxx > 10.0.0.41: ICMP echo request, id 26889, seq 55009, length 64
18:12:53.908648 IP xxx.xxx.xxx.xxx > 10.0.0.41: ICMP echo request, id 26889, seq 55009, length 64

I am running two L3 agents, which I've never had a problem with before. You can see my configs here: https://gist.github.com/thomas-p-wilson/a68ce2b5e8f0642b822f

The logs are showing nothing out of the ordinary.

Any thoughts or tips on what's going wrong?

Neutron duplicating inbound trafficCan ping instance but nothing more

Hi all!

I upgraded to IceHouse from Havana, and everything have come into a problem. Namely, I can ping into and out of my instances, but any other traffic gets lost. I can confirm that this is working with the exception that Neutron seems to be duplicating inbound traffic, which causes not a massive snarl-up for anything more complex than a ping.security group issue, as my neutron security group permits all incoming and outgoing traffic.

A tcpdump of a single PING request to my instance looks like:

18:12:53.908605 IP xxx.xxx.xxx.xxx > 10.0.0.41: ICMP echo request, id 26889, seq 55009, length 64
18:12:53.908612 IP xxx.xxx.xxx.xxx > 10.0.0.41: ICMP echo request, id 26889, seq 55009, length 64
18:12:53.908648 IP xxx.xxx.xxx.xxx > 10.0.0.41: ICMP echo request, id 26889, seq 55009, length 64
