More info on HA in Azure?

[JimMcGrady]

The documentation seems a bit light on detail. I have created a Service Principle in Azure and entered the data into my two firewalls as per these documents:

https://docs.paloaltonetworks.com/vm-series/9-1/vm-series-deployment/set-up-the-vm-series-firewall-o...

https://docs.microsoft.com/en-us/azure/active-directory/develop/howto-create-service-principal-porta...

The firewalls validate successfully. However, during failover, the secondary IP addresses dont move.

Should there be some config on the firewalls to say "move secondary IP addresses of interfaces A, B, C, and move public IP"?

Would there be corresponding config within Azure? How does the system know which interfaces need their addressing changed?

Hey @JimMcGrady ,

When doing a firewall failover, how long are you waiting between checking interface IPs? The reason for this is because using the Plugin for failover can take a few minutes. The recommended method to deploy VM series for high-availability in Azure is with two VM series deployed into two availability sets that sit in a load balancer sandwich.

Thanks,

Luke.
