Description Jeremy 2016-06-16 16:17:53 EDT 
Description of problem:Customer is requesting backport of the following upstream bug to RHOSP7.0.

https://bugs.launchpad.net/neutron/+bug/1544508

If neutron-meter-agent is installed and enabled, and a meter-label is created, all traffic between internal networks becomes NATed, which is unexpected and potentially causes firewall/routing issues. This happens because meter-agent does not define stateless flag during iptables initialization which later during _modify_rules in agent/linux/iptables_manager.py results in moving the following rules:

before:
-A POSTROUTING -j neutron-l3-agent-POSTROUTING
-A POSTROUTING -j neutron-postrouting-bottom

after:
-A POSTROUTING -j neutron-postrouting-bottom
-A POSTROUTING -j neutron-l3-agent-POSTROUTING
