如何使用 Power Shell 在 Windows 中打开防火墙端口

我想知道如何使用 Power Shell 在 Windows 中打开防火墙端口。有人可以编写一个用于打开防火墙端口的脚本吗？我在https://stackoverflow.com/questions/24760821/changing-windows-firewall-rules-with-powershell-open-close-a-specific-port但不明白该如何做。

我只想在 Windows 中打开一个端口：8983，因为当我执行应用程序（堆栈转储）时，它会显示pysolr.SolrError: Failed to connect to server at 'http://localhost:8983/solr/stackdump/admin/ping', are you sure that URL is correct?.Atlast，它显示：No connection could be made because the target machine actively refused it。

答案1

您可以参考指南这里。

打开80端口的命令是：

netsh advfirewall firewall add rule name="Open Port 80" dir=in action=allow protocol=TCP localport=80

您需要指定：

  • 规则名称
  • 方向
  • 是否允许连接
  • 使用的协议
  • 端口号

您可以从 Powershell 级别使用此命令。

如果您必须使用 Powershell，则可以使用类似以下脚本（也适用于端口 80）：

#==============================================================
# Creates a rule to open an incomming port in the firewall.
#==============================================================

#$numberAsString = read-host "type an port number"
#$mynumber = [int]$numberAsString


$port1 = New-Object -ComObject HNetCfg.FWOpenPort

$port1.Port = 80

$port1.Name = 'MyTestPort' # name of Port

$port1.Enabled = $true

$fwMgr = New-Object -ComObject HNetCfg.FwMgr

$profiledomain=$fwMgr.LocalPolicy.GetProfileByType(0)

$profiledomain.GloballyOpenPorts.Add($port1)

取自这里。

答案2

根据以下信息这个博客：

New-NetFirewallRule -DisplayName 'some-port' `
                    -LocalPort 1234 -Action Allow `
                    -Profile 'Public' `
                    -Protocol TCP `
                    -Direction Inbound

答案3

这是在防火墙上创建端口的另一种方法，其好处是系统将动态提示您输入与入站/出站、协议、允许/拒绝等相关的所有选项。


$rulename = Read-Host -Prompt "Enter rule name: "
$portNumber = Read-Host -Prompt "Enter Port Number: "
