Description

When you create an Azure firewall provider you are required to create a subnet called AzureFirewallSubnet. and them pass this subnet as the subnet Id of azure firewall currently there is no validation that this subnet has the correct required name and that other subnets do no have this name.

The problem with that is that when you do any change in the Firewall Subnet that requires the destruction of this subnet the firewall it is not marked for destruction.

Terraform (and AzureRM Provider) Version

Terraform v0.11.13

• provider.azurerm v1.23.0

• azurerm_subnet
• azurerm_firewall
