通过编程管理windows 防火墙
作者：肖波
最近项目中需要通过程序自动设置windows 防火墙，查了一下资料，可以通过命令行netsh firewall来实现。封装了一个类来实现对允许放开的程序(Allowed program)进行管理。管理其他内容比如放开端口等方法是类似的。
程序中用到一个公共类 RunProcess，这个类可从我的另一篇文章 一个C#写的调用外部进程类 获得
namespace WinFirewall
{
public enum TScope
{
ALL,
SUBNET,
CUSTOM,
}
public enum TMode
{
ENABLE,
DISABLE,
}
/**//// <summary>
/// Manage the allowed program with the Windows Firewall.
/// </summary>
public class AllowedProgram
{
Set AllowedProgram Help#region Set AllowedProgram Help
/**//*
set allowedprogram
[ program = ] path
[ [ name = ] name
[ mode = ] ENABLE|DISABLE
[ scope = ] ALL|SUBNET|CUSTOM
[ addresses = ] addresses
[ profile = ] CURRENT|DOMAIN|STANDARD|ALL ]
Sets firewall allowed program configuration.
Parameters:
program – Program path and file name.
name – Program name (optional).
mode – Program mode (optional).
ENABLE – Allow through firewall (default).
DISABLE – Do not allow through firewall.
scope – Program scope (optional).
ALL – Allow all traffic through firewall (default).
SUBNET – Allow only local network (subnet) traffic through firewall.
CUSTOM – Allow only specified traffic through firewall.
addresses – Custom scope addresses (optional).
profile – Configuration profile (optional).
CURRENT – Current profile (default).
DOMAIN – Domain profile.
STANDARD – Standard profile.
ALL – All profiles.
Remarks: \’scope\’ must be \’CUSTOM\’ to specify \’addresses\’.
Examples:
set allowedprogram C:\MyApp\MyApp.exe MyApp ENABLE
set allowedprogram C:\MyApp\MyApp.exe MyApp DISABLE
set allowedprogram C:\MyApp\MyApp.exe MyApp ENABLE CUSTOM
157.60.0.1,172.16.0.0/16,10.0.0.0/255.0.0.0,LocalSubnet
set allowedprogram program = C:\MyApp\MyApp.exe name = MyApp mode = ENABLE
set allowedprogram program = C:\MyApp\MyApp.exe name = MyApp mode = DISABLE
set allowedprogram program = C:\MyApp\MyApp.exe name = MyApp mode = ENABLE
scope = CUSTOM addresses =
157.60.0.1,172.16.0.0/16,10.0.0.0/255.0.0.0,LocalSubnet
