how to assign same floating ip to multiple network interfaces on Azure?

[ZuberP]

Hi,

I spun 2 PA VM-Series on Azure cloud. Both firewalls are up and running with HA but when I try to assign floating ip on public and private interfaces of firewall VMs as a secondary ip, I can do it on primary VM only. When I try to assign the same floating ip on secondary VM it gives me an error that ip already exists on primary VM. How do I achieve HA in this situation?

The secondary/floating IP is configured on the active firewall only.  The IP moves to the passive firewall during a fail-over event.  The VM-Series admin guide has the details.

Firewall switches over correctly when the primary goes down but on Azure backend side we can't have the same floating ip on secondary firewall VM, so traffic can't find next hop.
