按照下面的链接，我能够创建一个带有自定义 VHD 的 Azure VMSS，它支持负载平衡和自动缩放。
Updating VHD of Azure VM ScaleSet
但是使用上面的链接，我必须在同一个 VNET 中创建一个新的 VM，以便 RDP 进入 VMSS 中的 VM。
有什么方法可以直接 RDP 进入 VMSS 中的 VM 吗？

如果您不想创建跳转框，在某些地区 Azure Bastion 是替代方法。如果单击 VM 实例名称，您可以看到菜单刀片 Bastion

根据您的描述，我们可以在该负载均衡器中配置 NAT 规则。
这是一个模板，使用现有的 VHD 创建 VMSS 并配置 NAT 规则（3389）、负载平衡规则（端口 80）和 CPU 自动缩放：
