删除公共 IP 地址
若要从 NAT 网关中删除公共 IP，必须创建一个数组对象，其中不包含你要删除的 IP 地址。 例如，假设你为 NAT 网关配置了两个公共 IP 地址。 你想要删除其中一个 IP 地址。 与 NAT 网关关联的 IP 地址名为 public-ip-nat 和 public-ip-nat2。 若要删除 public-ip-nat2，需要为 PowerShell 命令创建一个仅包含 public-ip-nat 的数组对象。 应用该命令时，该数组会重新应用于 NAT 网关，这样，public-ip-nat 就成了唯一一个关联的公共 IP 地址。
## Place NAT gateway into a variable. ##
$ng = @{
Name = 'nat-gateway'
ResourceGroupName = 'test-rg'
}
$nat = Get-AzNatGateway @ng
## Place the existing public IP address associated with the NAT gateway into a variable. ##
$ip = @{
Name = 'public-ip-nat'
ResourceGroupName = 'test-rg'
}
$publicIP1 = Get-AzPublicIPaddress @ip
## Place the second public IP address into a variable. ##
$ip = @{
Name = 'public-ip-nat2'
ResourceGroupName = 'test-rg'
}
$publicIP2 = Get-AzPublicIPAddress @ip
## Place ONLY the public IP you wish to keep in the array. ##
$pipArray = $publicIP1
## Add the public IP address to the NAT gateway. ##
$nt = @{
NatGateway = $nat
PublicIpAddress = $pipArray
}
Set-AzNatGateway @nt
使用 az network nat gateway update 从 NAT 网关中删除公共 IP 地址。 Azure CLI 命令会替换这些值。 它不会删除值。 要删除公共 IP 地址，请在命令中添加要保留的所有 IP 地址。 省略要删除的值。 例如，假设你为 NAT 网关配置了两个公共 IP 地址。 你想要删除其中一个 IP 地址。 与 NAT 网关关联的 IP 地址名为 public-ip-nat 和 public-ip-nat2。 若要删除 public-ip-nat2，请在命令中省略该 IP 地址的名称。 该命令会将其中列出的 IP 地址重新应用于 NAT 网关。 它会删除所有未列出的 IP 地址。
## Place NAT gateway into a variable. ##
$ng = @{
Name = 'nat-gateway'
ResourceGroupName = 'test-rg'
}
$nat = Get-AzNatGateway @ng
## Place the existing public IP prefix associated with the NAT gateway into a variable. ##
$ip = @{
Name = 'public-ip-prefix-nat'
ResourceGroupName = 'test-rg'
}
$prefixIP1 = Get-AzPublicIPPrefix @ip
## Place the public IP prefix you created previously into a variable. ##
$ip = @{
Name = 'public-ip-prefix-nat2'
ResourceGroupName = 'test-rg'
}
$prefixIP2 = Get-AzPublicIPprefix @ip
## Place the public IP address variables into an array. ##
$preArray = $prefixIP1,$prefixIP2
## Add the IP address prefix to the NAT gateway. ##
$nt = @{
NatGateway = $nat
PublicIpPrefix = $preArray
}
Set-AzNatGateway @nt
删除公共 IP 前缀
若要从 NAT 网关中删除公共 IP 前缀，必须创建一个数组对象，其中不包含你要删除的 IP 地址前缀。 例如，假设你为 NAT 网关配置了两个公共 IP 前缀。 你想要删除其中一个 IP 前缀。 与 NAT 网关关联的 IP 前缀名为 public-ip-prefix-nat 和 public-ip-prefix-nat2。 若要删除 public-ip-prefix-nat2，需要为 PowerShell 命令创建一个仅包含 public-ip-prefix-nat 的数组对象。 应用该命令时，该数组会重新应用于 NAT 网关，这样，public-ip-prefix-nat 就成了唯一一个关联的前缀。
## Place NAT gateway into a variable. ##
$ng = @{
Name = 'nat-gateway'
ResourceGroupName = 'test-rg'
}
$nat = Get-AzNatGateway @ng
## Place the existing public IP prefix associated with the NAT gateway into a variable. ##
$ip = @{
Name = 'public-ip-prefix-nat'
ResourceGroupName = 'test-rg'
}
$prefixIP1 = Get-AzPublicIPPrefix @ip
## Place the secondary public IP prefix into a variable. ##
$ip = @{
Name = 'public-ip-prefix-nat2'
ResourceGroupName = 'test-rg'
}
$prefixIP2 = Get-AzPublicIPprefix @ip
## Place ONLY the prefix you wish to keep in the array. DO NOT ADD THE SECONDARY VARIABLE ##
$preArray = $prefixIP1
## Add the IP address prefix to the NAT gateway. ##
$nt = @{
NatGateway = $nat
PublicIpPrefix = $preArray
}
Set-AzNatGateway @nt
添加公共 IP 前缀
对于本示例，与 NAT 网关关联的现有公共 IP 前缀名为 public-ip-prefix-nat。
