En este inicio rápido, se usa una plantilla de Azure Resource Manager (plantilla de ARM) para implementar Azure Firewall en tres zonas de disponibilidad.
Note
Para nuevos despliegues, omite la propiedad del zones cortafuegos y deja que Azure gestione la asignación de zonas backend en regiones compatibles con ZR. Para usar la asignación gestionada por plataforma, descarga la plantilla, omite zones del recurso Microsoft.Network/azureFirewalls y despliega tu plantilla modificada. No elimines la configuración de zonas de un despliegue existente solo para obtener redundancia; los cortafuegos existentes elegibles se migran automáticamente.
Una plantilla de Azure Resource Manager es un archivo de notación de objetos JavaScript (JSON) que define tanto la infraestructura como la configuración de un proyecto. La plantilla usa sintaxis declarativa. Describe la implementación deseada sin escribir la secuencia de comandos de programación para crear la implementación.
Esta plantilla crea un entorno de red de prueba con un firewall. La red tiene una red virtual (VNet) con tres subredes: AzureFirewallSubnet, ServersSubnet y JumpboxSubnet. Cada una de las subredes ServersSubnet y JumpboxSubnet tiene una única máquina virtual Windows Server de doble núcleo.
El firewall está en la subred AzureFirewallSubnet y tiene una colección de reglas de aplicación con una única regla que permite el acceso a www.microsoft.com.
Una ruta definida por el usuario dirige el tráfico de red desde la subred ServersSubnet a través del firewall, en donde se aplican las reglas de firewall.
Para más información sobre Azure Firewall, vea Implementación y configuración de Azure Firewall mediante Azure Portal.
Si su entorno cumple los requisitos previos y está familiarizado con el uso de plantillas ARM, seleccione el botón Implementar en Azure. La plantilla se abrirá en Azure Portal.

En la plantilla se definen varios recursos de Azure:
- Microsoft.Storage/storageAccounts
- Microsoft.Network/routeTables
- Microsoft.Network/networkSecurityGroups
- Microsoft.Network/virtualNetworks
- Microsoft.Network/publicIPAddresses
- Microsoft.Network/networkInterfaces
- Microsoft.Compute/virtualMachines
- Microsoft.Network/azureFirewalls
Implementa la plantilla
Implemente la plantilla de ARM en Azure:
Seleccione Implementar en Azure para iniciar sesión en Azure y abrir la plantilla. La plantilla crea una instancia de Azure Firewall, la infraestructura de red y dos máquinas virtuales.
En el portal, en la página Create a sandbox setup of Azure Firewall with Zones, escriba o seleccione los valores siguientes:
- Grupo de recursos: seleccione Crear nuevo, escriba un nombre para el grupo de recursos y seleccione Aceptar.
- Nombre de la red virtual: escriba un nombre para la red virtual nueva.
- Nombre de usuario administrador: escriba un nombre de usuario para la cuenta de usuario de administrador.
- Contraseña de administrador: escriba una contraseña de administrador.
Lea los términos y condiciones, y seleccione Acepto los términos y condiciones indicados anteriormente y, después, seleccione Comprar. La implementación puede tardar 10 minutos o más en completarse.
Revisar los recursos desplegados
Explore los recursos que se crearon con el firewall.
Para información sobre la sintaxis y las propiedades de JSON de un firewall en una plantilla, consulte Microsoft.Network/azureFirewalls.
Limpiar recursos
Cuando ya no los necesite, puede quitar el grupo de recursos, el firewall y todos los recursos relacionados ejecutando el comando de PowerShell Remove-AzResourceGroup. Para quitar un grupo de recursos llamado MyResourceGroup, ejecute:
Remove-AzResourceGroup -Name MyResourceGroup
Si planea continuar con el tutorial de supervisión de firewall, no quite el firewall ni el grupo de recursos.
Siguientes pasos
A continuación, puede supervisar los registros de Azure Firewall.
