我能够以编程方式将单个规则添加到 Windows 防火墙（Server 2008 R2），但是我试图避免每个 IP 地址有多个规则，并且只想更新现有规则 RemoteAddresses。下面是我用来添加规则的代码，我正在尽我所能研究如何更新现有规则远程地址，但没有运气。

任何帮助表示赞赏！

string ip = "x.x.x.x";

INetFwRule2 firewallRule = (INetFwRule2)Activator.CreateInstance(Type.GetTypeFromProgID("HNetCfg.FWRule"));

firewallRule.Name = "Block Bad IP Addresses";
firewallRule.Description = "Block Nasty Incoming Connections from IP Address.";
firewallRule.Action = NET_FW_ACTION_.NET_FW_ACTION_BLOCK;
firewallRule.Direction = NET_FW_RULE_DIRECTION_.NET_FW_RULE_DIR_IN;
firewallRule.Enabled = true;
firewallRule.InterfaceTypes = "All";
firewallRule.RemoteAddresses = ip;

INetFwPolicy2 firewallPolicy = (INetFwPolicy2)Activator.CreateInstance(Type.GetTypeFromProgID("HNetCfg.FwPolicy2"));
firewallPolicy.Rules.Add(firewallRule);

下面的代码对我有用：

INetFwPolicy2 firewallPolicy = (INetFwPolicy2) Activator.CreateInstance(Type.GetTypeFromProgID("HNetCfg.FwPolicy2"));

var rule = firewallPolicy.Rules.Item("Block Bad IP Addresses"); // Name of your rule here
rule.Name = "Block Block Block"; // Update the rule here. Nothing else needed to persist the changes

除了 amdmax 的回答（对不起，我不能添加评论）我发现没有简单的方法调用来检查规则是否存在所以我想出了这个来确保创建规则是否存在：

  INetFwPolicy2 firewallPolicy = (INetFwPolicy2)Activator.CreateInstance(
      Type.GetTypeFromProgID("HNetCfg.FwPolicy2"));

  INetFwRule firewallRule = firewallPolicy.Rules.OfType<INetFwRule>().Where(x => x.Name == RULE_NAME).FirstOrDefault();

  if (firewallRule == null)
  {
    firewallRule = (INetFwRule)Activator.CreateInstance(Type.GetTypeFromProgID("HNetCfg.FWRule"));
    firewallRule.Name = RULE_NAME;
    firewallPolicy.Rules.Add(firewallRule);
  }

我发现这个包可以通过 nuget WindowsFirewallHelper获得

PM> install-package WindowsFirewallHelper

例子

var rule = FirewallManager.Instance.Rules.Where(o => 
    o.Direction == FirewallDirection.Inbound &&
    o.Name.Equals("Allow Remote Desktop")
).FirstOrDefault();

if (rule != null)
{
    //Update an existing Rule
    rule.RemoteAddresses = new IAddress[]
    {
        SingleIP.Parse("192.168.184.1"),
        SingleIP.Parse("192.168.184.2")
    };

    return;
}

//Create a new rule
rule = FirewallManager.Instance.CreateApplicationRule(
     FirewallManager.Instance.GetProfile().Type,
     @"Allow Remote Desktop",
     FirewallAction.Allow,
     null
);

rule.Direction = FirewallDirection.Inbound;
rule.LocalPorts = new ushort[] { 3389 };
rule.Action = FirewallAction.Allow;
rule.Protocol = FirewallProtocol.TCP;
rule.Scope = FirewallScope.All;
rule.Profiles = FirewallProfiles.Public | FirewallProfiles.Private;
rule.RemoteAddresses = new IAddress[] { SingleIP.Parse("192.168.184.1") };

FirewallManager.Instance.Rules.Add(rule);
