[kolla] neutron-l3-agent namespace NAT table not working?


Is this qrouter namespace created with all those rules in container or in the host directly?
Do You have qr-xxx and qg-xxx ports from br-int in this qrouter namespace?

It comes up, sets up the iptables rules in the qrouter namespace (and I can see these using "ip netns...") but traffic isn't having DNAT or SNAT applied. What's most strange is that manually adding a LOG jump target to the iptables nat PRE/POSTROUTING chains (after enabling nf logging sent to the host kernel, confirmed that works) doesn't result in any log entries. It's as if the nat table isn't being applied at all for any packets traversing the qrouter namespace. This is driving me crazy :)
