I did verify it in Mitaka and I don't see any issues with the 'sg' port
and related rules with respect to failover.

So we can close this issue as we discussed last week.

Title:
  SNAT HA failed because of missing nat rule in snat namespace iptable

Status in neutron:
  Invalid

Bug description:
  I have a mitaka openstack deployment with neutron DVR enabled. When I
  try to test the snat HA failover I found that even though the snat
  namespace was created on the other backup node, it doesn't has any nat
  rule in snat namespace iptable. And run "ip a" in the sant namespace
  you will find the sg port is missing.

  Here is what I found on the second neutron network node
