Quickstart: Een Azure Firewall en een firewallbeleid maken - ARM-sjabloon
In deze quickstart gebruikt u een Azure Resource Manager-sjabloon (ARM-sjabloon) om een Azure Firewall en een firewallbeleid te maken. Het firewallbeleid heeft een toepassingsregel die verbindingen www.microsoft.com met en een regel toestaat die verbindingen met Windows Update toestaat met behulp van de FQDN-tag WindowsUpdate . Een netwerkregel staat UDP-verbindingen met een tijdserver toe op 13.86.101.172.
Ip-groepen worden ook gebruikt in de regels om de bron-IP-adressen te definiëren.
Een Azure Resource Manager-sjabloon is een JSON-bestand (JavaScript Object Notation) dat de infrastructuur en configuratie voor uw project definieert. Voor de sjabloon is declaratieve syntaxis vereist. U beschrijft de beoogde implementatie zonder de reeks programmeeropdrachten te schrijven om de implementatie te maken.
Zie Wat is Azure Firewall Manager?voor meer informatie over Azure Firewall Manager.
Zie Wat is Azure Firewall? voor meer informatie over Azure Firewall.
Zie IP-groepen in Azure Firewall voor meer informatie over IP-groepen.
Als uw omgeving voldoet aan de vereisten en u benkend bent met het gebruik van ARM-sjablonen, selecteert u de knop Implementeren naar Azure. De sjabloon wordt in Azure Portal geopend.
Vereisten
- Een Azure-account met een actief abonnement. Gratis een account maken
De sjabloon controleren
Met deze sjabloon maakt u een virtueel hubnetwerk, samen met de benodigde resources ter ondersteuning van het scenario.
De sjabloon die in deze quickstart wordt gebruikt, komt uit Azure-snelstartsjablonen.

Er worden meerdere Azure-resources gedefinieerd in de sjabloon:
- Microsoft.Network/ipGroups
- Microsoft.Network/firewallPolicies
- Microsoft.Network/firewallPolicies/ruleCollectionGroups
- Microsoft.Network/azureFirewalls
- Microsoft.Network/virtualNetworks
- Microsoft.Network/publicIPAddresses
De sjabloon implementeren
Het ARM-sjabloon implementeren in Azure:
Selecteer Implementeren in Azure om u aan te melden bij Azure en de sjabloon te openen. Met de sjabloon maakt u een Azure-firewall, een virtuele WAN en virtuele hub, de netwerkinfrastructuur en twee virtuele machines.
Typ of selecteer in de portal op de pagina Firewall en FirewallPolicy maken met regels en Ipgroups de volgende waarden:
- Abonnement: Selecteer uit bestaande abonnementen.
- Resourcegroep: Selecteer uit bestaande resourcegroepen of selecteer Nieuwe maken en selecteer OK.
- Regio: Selecteer een regio.
- Firewallnaam: typ een naam voor de firewall.
Selecteer Controleren en maken en selecteer vervolgens Maken. De implementatie kan 10 minuten of langer duren.
Geïmplementeerde resources bekijken
Nadat de implementatie is voltooid, ziet u de volgende vergelijkbare resources.
Resources opschonen
Wanneer u de resources die u met de firewall hebt gemaakt niet meer nodig hebt, verwijdert u de resourcegroep. Hiermee verwijdert u de firewall en alle gerelateerde resources.
Als u de resourcegroep wilt verwijderen, roept u de cmdlet Remove-AzResourceGroup aan:
Remove-AzResourceGroup -Name "<your resource group name>"
