Hi all,

OVN support stateless NAT operations [1] for use case of 1:1 mapped between inner and external ips, i.e dnat_and_snat rule. In openstack is the floating ip use-case.
Looking on ml2 ovn support it seem that it only support floating ip with connection tracking. Can ml2 ovn support also the stateless NAT option? Is there concerns using stateless NAT?
