Inicio rápido: Creación de una instancia de Azure Firewall con varias direcciones IP públicas: plantilla de Resource Manager
En este inicio rápido, se usa una plantilla de Azure Resource Manager para implementar una instancia de Azure Firewall con varias direcciones IP públicas desde un prefijo de direcciones IP públicas. El firewall implementado tiene reglas de recopilación de reglas NAT que permiten conexiones RDP a dos máquinas virtuales Windows Server 2019.
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.
Para más información acerca de Azure Firewall con varias direcciones IP públicas, consulte Implementación de una instancia de Azure Firewall con varias direcciones IP públicas mediante Azure PowerShell.
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
- Una cuenta de Azure con una suscripción activa. Cree una cuenta gratuita.
Revisión de la plantilla
Esta plantilla crea una instancia de Azure Firewall con dos grupos de direcciones IP públicas, junto con los recursos necesarios para admitir Azure Firewall.

En la plantilla se definen varios recursos de Azure:
- Microsoft.Network/networkSecurityGroups
- Microsoft.Network/publicIPPrefix
- Microsoft.Network/publicIPAddresses
- Microsoft.Network/virtualNetworks
- Microsoft.Compute/virtualMachines:
- Microsoft.Storage/storageAccounts
- Microsoft.Network/networkInterfaces
- Microsoft.Network/azureFirewalls
- Microsoft.Network/routeTables
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 an Azure Firewall with multiple IP public addresses (Crear una instancia de Azure Firewall con varias direcciones públicas), escriba o seleccione los valores siguientes:
- Suscripción: seleccione una de las suscripciones existentes.
- Grupo de recursos: seleccione uno de los grupos de recursos existentes o elija Crear nuevo y, luego, Aceptar.
- Ubicación: Seleccionar una ubicación
- Nombre de usuario de administrador: escriba un nombre de usuario para la cuenta de usuario de administrador.
- Contraseña de administrador: escriba una contraseña o clave de administrador.
Seleccione Acepto los términos y condiciones indicadas anteriormente y, después, seleccione Comprar. La implementación puede tardar 10 minutos o más en completarse.
Validación de la implementación
En Azure Portal, revise los recursos implementados. Anote las direcciones IP públicas del firewall.
Use la conexión a Escritorio remoto para conectarse a las direcciones IP públicas del firewall. En las conexiones correctas, se usan reglas NAT del firewall para permitir la conexión con los servidores backend.
Limpieza de recursos
Cuando ya no necesite los recursos que ha creado con el firewall, elimine el grupo de recursos. Al eliminar el grupo de recursos, se quitará el firewall y todos los recursos que estén relacionados con este.
Para eliminar el grupo de recursos, llame al cmdlet Remove-AzResourceGroup:
Remove-AzResourceGroup -Name "<your resource group name>"
