Limited support for IPv6, from a load balancer to VMs. But can't configure to point to a firewall (NVA) as a limitation exists that multiple NICs cant be attached to the VM (as in a typical routing firewall).
Not currently in plan. We are exploring other solutions for this scenario.

Very disappointed in the new Standard Load Balancer and the fact that the HA feature can't be used externally. Based on conversations with Palo Alto and Fortinet, this was their plan to provide seamless firewall high availability without trickery.
