Azure NGFW active-active HA and Panorama requirements

L0 Member

Hi, we're currently evaluating the use of NGFW's for a new Azure deployment.

 

Ideally, we need to deploy NGFW in an active-active HA pattern behind an Azure internal load balancer.

 

The documentation appears to state that Panorama is required to support this configuration. Is this a hard requirement? Is it possible to enable active-active with Config sync without Panorama?

 

Thanks.

Hi Andrew,

 

we talking here about two different things. the documentation is talking about Azure Autoscaling no we didnt use here a native HA configuration both firewalls are working independently. the is no Session Sync. the Panorama is taking care here about the increase and decrease of VM-Instances inside the VMSS and this is done via the AppInsight Metrics. 

 

the Native HA configuration is working in Azure but without a Loabbalancer in the Front or Back. look here about the Setup https://docs.paloaltonetworks.com/vm-series/9-0/vm-series-deployment/set-up-the-vm-series-firewall-o...

 

I hope that helped you?

 

Regards,

Torsten

Hello

 

We have configured HA on Azure, but it turns out that is not the best setup. You don't need a loadbalancer (and therefore no additional virtual router if you have more than one interface behind a loadbalancer).

Unfortunately the failover (regardless of triggered manual or due to an failure) is very slow. The command "hey Azure, shift IP from from interface A to interface B" is triggered immediately. In our environment (trusted, untrusted + two additional IPs with public IP) it typically takes 3 up to 5 Minutes until the failover is completed.

Hi Jörg,

 

thats correct and thats a normal behaviour in Azure. The Problem here is the API call from Azure to detach and attach the interface.

 

Regards,

Torsten
