Title:
  neutron port forwarding doesn't work

Status in neutron:
  Invalid

Bug description:
  I found a bug about neutron port forwarding and Detailed operations are as follows:
  first,create a VPC,
   1)openstack address scope create my_project_id
   2)openstack network create my_network
   3)openstack subnet pool create <network id> --address-scope <project id> --pool-prefix "10.0.114.0/24"
   4)openstack subnet create --network <network id> --subnet-pool <subnet pool id> --subnet-range 10.0.114.0/25 <subnet name>
   5)openstack router create my_router
   6)openstack router set jidd-router1 --external-gateway <exxternal network id> --enable-snat
   7)openstack router add subnet <router id> <subnet id>
  second,create a vm by the network above
  And,config floating ip port forwarding.

  for example, external ip and port: 10.142.254.158, 8870; internal port: 10.0.99.29,8870
  It can not reach form a external ip to 10.142.254.158 using telnet.

  Found that, packet is dropped in snat namespace, becase of packet is
  marked different labels between qg-xxx interface and sg-xxx interface.

  hit rules:
  0     0 DROP       all  --  *      sg-4ddcbea1-c6  0.0.0.0/0            0.0.0.0/0            mark match ! 0x4000000/0xffff0000
