Azure ALB sandwich with vm-series

[CHOE-KyungJun]

Dear Team,

I am aware that Sandwich deployments are possible on AWS.

I would like to know if Sandwich configuration is possible on Azure as well.

Azure knows that only one load balancer is connected.

If anyone has a successful sandwich configuration, please let me know.

I would appreciate it if you could share any related documents.

Thanks in advance,
Kyungjun,

Hi Kyungjun,

Please refer to reference architecture document available at https://www.paloaltonetworks.com/resources/guides/azure-architecture-guide

As part of this document "Design Model" section has details on how we will be able to use Public and internal load balancers to sandwich VM series.

Please do reach out to me if you have any additional queries in this regard.

Thanks,

RAVI

@rpegada Thank you for your reply

I've already checked the Design Model.

The model seems to be configured using Azure load balancer and application gateway.

If so, are the above two services necessary to configure Sandwich?

Thanks in advance,

Yes, we need to have Application Gateway/Public loadlalancer on Public side and Internal load balancer on Private side of VM Series firewall.

Thanks,

The document shows internal and external load balancer, both with SKU of standard, not Gateway. It also lists Application Gateway Optional.

Do we have to deploy Application Gateway in order to make it work?

Thanks

It depends on the type of traffic. If you want to secure Web traffic you need to have Application Gateway on the public side and Standard Public load balancer for other traffic(that include web traffic as well ).

Its not mandatory to only use Application gateway
