Title:
  NAT reflection with OVN on xena not working

Status in neutron:
  Fix Released

Bug description:
  ---- Problem
  When a VM-A located in network 'INTRANET' tries to reach a VM-B also located in network 'INTRANET', but using a FIP with port forwarding, the connection does not work.

  So if on of my FIPs has the IP 1.1.1.1 and that fip forwards port 25
  to VM-B i do this on VM-A

  telnet 1.1.1.1 25

  The connection stalls.

  ---- Setup

  I have the following setup
   - Xena
   - OVN
   - DVR disabled
   - Multiple FIPs
   - multiple computes, one controller
   - Since non DVR, all FIPs are routed through the controller

  The topology looks like this
   - 'INTRANET' network
   - 'K8S' network

  ---- Additional observation

  - It does not matter if VM-A and VM-B are located on the same or different computes
  - A VM-C located in network K8S can reach VM-B
  - A VM-D located in network K8S can reach VM-C located in K8S using a non-port forward FIP
  - Connection to 1.1.1.1 from the outer world are working without any issues
