Inicio rápido: Implementación de Azure Firewall con Availability Zones: plantilla de Resource Manager
En este inicio rápido, se usa una plantilla de Azure Resource Manager para implementar una instancia de Azure Firewall en tres instancias de Availability Zones.
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. Se 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 señala 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 de Resource Manager, seleccione el botón Implementar en Azure. La plantilla se abrirá en Azure Portal.
Requisitos previos

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
Implementación de la plantilla
Implementación de la plantilla de Resource Manager 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 (Crear una configuración de espacio aislado de Azure Firewall), 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.
Revisión de los recursos implementados
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.
Limpieza de recursos
Cuando ya no los necesite, puede quitar el grupo de recursos, el firewall y todos los recursos relacionados mediante la ejecución del 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.
Pasos siguientes
A continuación, puede supervisar los registros de Azure Firewall.
