快速入门：创建具有多个公共 IP 地址的Azure Firewall - Bicep

在本快速入门中，使用 Bicep 文件，从公共 IP 地址前缀部署具有多个公共 IP 地址的 Azure Firewall。部署的防火墙具有 NAT 规则收集规则，允许 RDP 连接到两个Windows Server 2019虚拟机。

Bicep是一种特定于域的语言（DSL），它使用声明性语法来部署Azure资源。它提供简明的语法、可靠的类型安全性以及对代码重用的支持。 Bicep为Azure中的基础结构即代码解决方案提供最佳创作体验。

有关具有多个公共 IP 地址的Azure Firewall的详细信息，请参阅使用 Azure PowerShell的Azure Firewall。

先决条件

该模板定义多个Azure资源：

部署 Bicep 文件

将Bicep文件保存到本地计算机为 main.bicep。

使用Azure CLI或Azure PowerShell部署Bicep文件。

CLI
PowerShell

az group create --name exampleRG --location chinaeast
az deployment group create --resource-group exampleRG --template-file main.bicep --parameters adminUsername=<admin-username>

New-AzResourceGroup -Name exampleRG -Location chinaeast
New-AzResourceGroupDeployment -ResourceGroupName exampleRG -TemplateFile ./main.bicep -adminUsername "<admin-username>"

注意

将 <admin-username> 替换为后端服务器的管理员用户名。

系统会提示输入管理员密码。

部署完成后，可看到一条指示部署成功的消息。

验证部署

在Azure门户中，查看已部署的资源。记下防火墙公共 IP 地址。

使用远程桌面连接连接到防火墙公共 IP 地址。成功的连接证明了防火墙 NAT 规则允许连接到后端服务器。

清理资源

如果不再需要为防火墙创建的资源，请删除资源组。此操作将删除防火墙和所有相关资源。

若要删除资源组，请使用 Remove-AzResourceGroup cmdlet：

Remove-AzResourceGroup -Name "exampleRG"
