+* Floating IP Port Forwarding in provider networks and with distributed routing
+
+  Currently, when provider network types like ``vlan`` or ``flat`` are plugged
+  to a router as internal networks while the ``enable_distributed_floating_ip``
+  configuration option is enabled, Floating IP port forwardings
+  which are using such router will not work properly.
+  Due to an incompatible setting of the router to make traffic in the vlan/flat
+  networks to be distributed but port forwardings are always centralized in
+  ML2/OVN backend.
