我正在尝试读取 ARM 模式网络安全组中的现有规则，但奇怪的是 SourceAddressPrefix 属性（包含有关列入白名单的 IP 范围的信息的属性）报告为布尔值（如“True”或“False” ) 字符串形式。

我已经尝试使用Get-AzureRmNetworkSecurityGroup和读取该::SecurityRules属性来检索组，并且也尝试$nsg | Get-AzureRmNetworkSecurityRuleConfig过$nsg | Get-AzureRmNetworkSecurityRuleConfig -Name MyRule. 在每种情况下SourceAddressPrefix，返回的规则都是“真”或“假”。

如果没有该值，我无法判断是否已经为我正在检查的 IP 制定了规则。只要名称和优先级不同，系统就可以让我设置多个具有相同细节的规则，所以我现在正在创建重复项。

我认为这是某种安全“功能”？有没有办法检索门户中显示的实际 IP CIDR 范围？

编辑 - 由于这个来来去去，我发布了完整的代码

该代码获取分配给所有 NIC 的 IP 地址，$proxyResGrp并尝试将它们列入端口 80 和 443 的源资源组中的白名单。

proxyResGrp = "arr"
originResGrps = "int", "uat", "auth", "live"

elect-AzureRmSubscription -SubscriptionID $subscriptionId -ErrorAction SilentlyContinue -ErrorVariable err | Out-Null
f ( $err ) {
    Login-AzureRmAccount
    Select-AzureRmSubscription -SubscriptionID $subscriptionId -ErrorAction Stop | Out-Null



 get the source IPs for the arr
proxyIPs =  Get-AzureRmNetworkInterface -ResourceGroupName $proxyResGrp | % {
                $_.IpConfigurations | % {
                    if ( $_.PublicIpAddress.Id -like '*Microsoft.Network/publicIPAddresses*' )
                    {
                        $ipAddress = Get-AzureRmResource -ResourceId ($_.PublicIpAddress.Id)
                        $ip = Get-AzureRmPublicIpAddress -ResourceGroupName $ipAddress.ResourceGroupName -Name $ipAddress.Name
                        return @{ IPAddress = $ip.IpAddress; Name = $_.Name }
                    }
                }
            }

 get NSG for each source resourceGroup and add the inbound rules
originResGrps | % {
    $originResGrp = $_
    Get-AzureRmNetworkSecurityGroup -ResourceGroupName $originResGrp | % {
        # have to re-get the NSG for some reason
        $nsg = $_

        $nsg.SecurityRules | ? { $_.SourceAddressPrefix = $arrIP.IPAddress -and $_.DestinationPortRange -eq "80" }
        $rules = $nsg.SecurityRules

        $maxPriority = $rules | Sort Priority -Descending | select Priority -First 1 | % { $_.Priority }

        $isChanged = $false
        foreach ( $proxyIP in $proxyIPs )
        {
            # HTTP
            # $rule = $rules | ? { $_.Name -eq "HTTP-$($arrIP.Name.ToUpper())" }
            $rule = $rules | ? { $_.SourceAddressPrefix -eq $proxyIP.IPAddress -and $_.DestinationPortRange -eq "80" }
            if ( ! $rule )
            {
                $maxPriority += 100

所以这对我有用：

$a = Get-AzureRmNetworkSecurityGroup -Name $NSG_Name -ResourceGroupName $RG_Name
PS C:\WINDOWS\system32> $a.SecurityRules[1].sourceaddressprefix
10.0.0.0/23
PS C:\WINDOWS\system32> $a.SecurityRules[0].sourceaddressprefix
*

我建议你更新你的 powershell 模块。
