问题描述
我通过从 3 个数组中获取对象并填充 $Params 以发出 New-NetFirewallRule 命令,在 PowerShell 上添加 Windows 防火墙规则。我不明白为什么我的第一个命令失败并显示错误“端口号不正确”
代码:
$All = @( '13.79.172.43','13.69.228.5','1.1.1.1' )
$AllPorts = @( '8883,443','443','80' )
$AllProtocols = @( 'TCP','TCP','TCP' )
for ($i = 0; $i -lt $All.Count; $i++) {
$Params = @{
"displayName" = '"Block-WiFi-' + $i
"Name" = 'Block-WiFi-' + $i
"Direction" = 'Inbound'
"InterfaceType" = 'Wireless'
"Action" = 'Block'
"RemoteAddress" = $All[$i]
"LocalPort" = $AllPorts[$i]
"Protocol" = $AllProtocols[$i]
}
# Add Windows Firewall RUle
New-NetFirewallRule @Params
# Check what is going on
Write-Host "Address: $($All[$i]) | Port: $($AllPorts[$i]) | Protocol: $($AllProtocols[$i])"
Write-Host "----------------------------------------------------------------------------------"
Start-Sleep 2
}
当我手动尝试命令时,它可以工作:
New-NetFirewallRule -displayName "Block-Wireless-In-01" -Name "Block-Wireless-In-01" -Direction Inbound -InterfaceType Wireless -Action Block -RemoteAddress 13.79.172.43 -LocalPort 8883,443 -Protocol TCP
此外,当我尝试添加 @Params "LocalPort" = 8883,443 时,添加的规则没有错误。
谁能帮助我,因为它已经让我发疯了两天。
提前致谢!
解决方法
Parameter -LocalPort
of New-NetFirewallRule
被声明为数组 String[]
。所以当你想传递多个端口时,你必须创建一个嵌套数组:
$AllPorts = @( @('8883','443'),'443','80' )
