C++ 修改防火墙firewall设置（Windows）

1、简介

防火墙（英语：Firewall）技术是通过有机结合各类用于安全管理与筛选的软件和硬件设备，帮助计算机网络于其内、外网之间构建一道相对隔绝的保护屏障，以保护用户资料与信息安全性的一种技术。 C++ 修改防火墙firewall设置（Windows）

1.1 防火墙概述

所谓“防火墙”是指一种将内部网和公众访问网（如Internet）分开的方法，它实际上是一种建立在现代通信网络技术和信息安全技术基础上的应用性安全技术，隔离技术。越来越多地应用于专用网络与公用网络的互联环境之中，尤其以接入Internet网络为最甚。 C++ 修改防火墙firewall设置（Windows）

1.2 入站，还是出站？

入站是外网的人访问我；出站是我访问外网。 入站开了本机的443端口，意味着外网的人可以通过443端口访问你的HTTPS服务；出站设置一般是允许访问外网IP的443端口。

入站端口：就是别人来访问我的某个端口。比如我设置阻止连接所有站点的入站端口8080，就是所有其他主机不能访问我这台服务器的8080端口。 出站端口：就是我去访问别人的某个端口。比如我设置阻止连接所有站点的出站端口3306，就是我不能访问所有其他网址的3306端口 C++ 修改防火墙firewall设置（Windows）

1.3 防火墙规则优先级

Windows防火墙的规则扫描有它自己特定的顺序，其优先级为： 1、只允许安全连接 2、阻止连接 3、允许连接 4. 默认规则（如果没有设置，那就是默认阻止）

As soon as a network packet matches a rule, that rule is applied, and processing stops. For example, an arriving network packet is first compared to the authenticated bypass rules. If it matches one, that rule is applied and processing stops. The packet is not compared to the block, allow, or default profile rules. If the packet does not match an authenticated bypass rule, then it is compared to the block rules. If it matches one, the packet is blocked, and processing stops, and so on.

2、系统界面方式

打开控制面板，点击系统和安全。 C++ 修改防火墙firewall设置（Windows） 点击Windows Defender防火墙。 C++ 修改防火墙firewall设置（Windows） 点击右侧的高级设置。 C++ 修改防火墙firewall设置（Windows） 点击入站规则，然后点击右侧的新建规则。 C++ 修改防火墙firewall设置（Windows） 然后勾选端口，点击下一步。 C++ 修改防火墙firewall设置（Windows） 接着填写开放的端口号（如5000）。 C++ 修改防火墙firewall设置（Windows） 接着如果是允许连接的话，直接点击下一步。 C++ 修改防火墙firewall设置（Windows） 接着直接点击下一步。 C++ 修改防火墙firewall设置（Windows） 接着填写名字和描述，点击完成。 C++ 修改防火墙firewall设置（Windows） 在入站规则中出现了刚才添加的规则。 C++ 修改防火墙firewall设置（Windows）

3、命令行方式

C++ 修改防火墙firewall设置（Windows）

Win10 如何使用cmd命令行配置防火墙：

3.1 防火墙基本状态设置

# 查看当前防火墙状态：
netsh advfirewall show allprofiles
netsh advfirewall show allprofiles state

C++ 修改防火墙firewall设置（Windows）

# 恢复初始防火墙设置：
netsh advfirewall reset

# 设置默认输入和输出策略：
# 设置为允许
netsh advfirewall set allprofiles firewallpolicy allowinbound,allowoutbound
# 设置为拒绝
netsh advfirewall set allprofiles firewallpolicy blockinbound,blockoutbound

# 显示默认的入站和出站防火墙行为。
netsh advfirewall show allprofiles firewallpolicy

C++ 修改防火墙firewall设置（Windows）C++ 修改防火墙firewall设置（Windows）

# 显示日志记录设置。
netsh advfirewall show allprofiles logging

C++ 修改防火墙firewall设置（Windows）

# 开启防火墙：
netsh advfirewall set allprofiles state on

C++ 修改防火墙firewall设置（Windows）

#关闭防火墙：
netsh advfirewall set allprofiles state off

C++ 修改防火墙firewall设置（Windows）

3.2 入站出站规则设置

  • 添加入站规则
# 允许
netsh advfirewall firewall add rule name=xiaomu1 dir=in action=allow protocol=tcp localport=5000

# 阻止
netsh advfirewall firewall add rule name=xiaomu1 dir=in action=block protocol=tcp localport=5000

C++ 修改防火墙firewall设置（Windows）

  • 添加出站规则
# 允许
netsh advfirewall firewall add rule name=xiaomu1 dir=out action=allow protocol=tcp localport=5000

# 阻止
netsh advfirewall firewall add rule name=xiaomu1 dir=out action=block protocol=tcp localport=5000

C++ 修改防火墙firewall设置（Windows）

  • 删除入站出站规则
# 删除入站允许
netsh advfirewall firewall delete rule name=test001 dir=in action=allow protocol=tcp localport=445

# 删除出站允许
netsh advfirewall firewall delete rule name=test001 dir=out action=allow protocol=tcp localport=445
  • bat批处理文件实现添加防火墙出入站规则：
@echo off

rem 以管理员权限执行命令
%1 mshta vbscript:CreateObject("Shell.Application").ShellExecute("cmd.exe","/c %~s0 ::","","runas",1)(window.close)&&exit
cd /d "%~dp0"

rem 设置指定端口变量和出入站规则名称
set INPUT_RULE_NAME=xiaomu_in
set OUT_RULE_NAME=xiaomu_out
set PORT=27700-27702,3316,5000-5010

rem 创建入站规则
echo Input Rule
netsh advfirewall firewall show rule name=%INPUT_RULE_NAME% >nul
rem 如果已经存在则先删除
if not ERRORLEVEL 1 (
    netsh advfirewall firewall delete rule name=%INPUT_RULE_NAME% >nul
) 
netsh advfirewall firewall add rule name=%INPUT_RULE_NAME% dir=in action=allow protocol=TCP localport=%PORT%
echo %INPUT_RULE_NAME% Create Successed!

rem 创建出站规则
echo Output Rule
netsh advfirewall firewall show rule name=%OUT_RULE_NAME% >nul
rem 如果已经存在则先删除
if not ERRORLEVEL 1 (
   netsh advfirewall firewall delete rule name=%OUT_RULE_NAME% >nul
) 
netsh advfirewall firewall add rule name=%OUT_RULE_NAME% dir=out action=allow protocol=TCP localport=%PORT%
echo %OUT_RULE_NAME% Create Successed!

echo Done!
pause

3.3 其他设置

  • 允许并阻止ping 您可以使用netsh来控制给定系统如何响应ping请求以及是否响应。以下两个netsh命令显示了如何阻止然后打开Windows防火墙来ping请求：
netsh advfirewall firewall add rule name="All ICMP V4" dir=in action=block protocol=icmpv4
netsh advfirewall firewall add rule name="All ICMP V4" dir=in action=allow protocol=icmpv4
  • 启用程序 另一个常见任务是为给定程序打开Windows防火墙。以下示例说明了如何添加使Windows Live Messenger通过Windows防火墙工作的规则：
netsh advfirewall firewall add rule name="Allow Messenger" dir=in action=allow program="C:\programfiles\messenger\msnmsgr.exe"
  • 启用远程管理 另一个常见要求（尤其是在设置新系统时）是启用远程管理，以便Microsoft Management Console等工具可以连接到远程系统。要打开Windows防火墙进行远程管理，可以使用以下命令：
netsh advfirewall firewall set rule group="remote administration" new enable=yes
  • 启用远程桌面连接 对设置的大多数服务器系统所做的第一件事就是启用远程桌面连接用于轻松的远程系统管理。以下命令显示如何使用netsh打开Windows防火墙进行远程桌面连接：
netsh advfirewall firewall set rule group="remote desktop" new enable=Yes
  • 导出和导入防火墙设置文件 配置Windows防火墙后，最好导出设置，以便以后可以轻松地重新应用它们或将其导入另一个系统。
netsh advfirewall export "C:\temp\WFconfiguration.wfw"
netsh advfirewall import "C:\temp\WFconfiguration.wfw"
  • 关闭5900端口
netsh advfirewall firewall add rule name= “deny tcp 5900″ dir=in protocol=tcp localport=5900 action=block
  • 设置Ip禁止
# remoteip 允许的IP，多个IP用逗号分割
netsh advfirewall firewall add rule name="test" dir=in action=allow protocol=TCP localport=3389,135 remoteip=10.10.12.20,10.10.12.21

3.4 telnet检测端口

完成之后，可以用telnet测试端口是否开放。 打开命令行窗口，输入命令：telnet 127.0.0.1 5000，如果出现下图的界面就说明该端口已经开放。 C++ 修改防火墙firewall设置（Windows） 如果telnet没有安装的话，请按照如下步骤操作。 使用win+R键打开运行程序，在输入框里输入：OptionalFeatures，点击确定。 C++ 修改防火墙firewall设置（Windows） 勾选上Telnet客户端并点击确定，就会开始安装telnet客户端。 重新打开一个cmd窗口输入telnet命令，如下所示表明telnet客户端安装成功。 C++ 修改防火墙firewall设置（Windows）

C++ 修改防火墙firewall设置（Windows）

4.3 COM（Windows Vista and later）

高级安全 Windows 防火墙和此处记录的相关防火墙技术使开发人员能够共享 Internet 连接、使用防火墙保护连接并提供网络地址转换 （NAT）。

微软已经发布了几个版本的防火墙产品，每个版本都建立在以前的技术之上。当前版本“高级安全 Windows 防火墙”允许创建极其具体的防火墙规则。

  • 具体技术如下（此处从最新到最旧列出）：

    • 高级安全 Windows 防火墙是最新版本。它最初与Windows Vista一起发布。
    • Windows Firewall 最初是作为 Windows XP Service Pack 2 （SP2） 的一个组件发布的。
    • IPv6 Internet Connection Firewall 作为 Windows XP 高级网络包的组件发布。它在后续版本的 Windows 中不可用。
    • Internet 连接共享和 Internet 连接防火墙最初是在 Windows XP 中发布的，在 Windows Vista 中受支持。它可能在后续版本的 Windows 中被更改或不可用。

  • 添加防火墙规则 This C++ file includes sample code that adds a LAN rule to the currently active profiles using the Microsoft Windows Firewall APIs.
