使用 API 更新现有防火墙规则 [英] Updating existing firewall rule using API

问题描述

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，我正在尽最大努力研究如何更新现有规则远程地址，但没有运气.

I am able to pro grammatically add individual rules to the Windows Firewall (Server 2008 R2), however I am trying to avoid multiple rules per IP address, and would just like to update the existing rule RemoteAddresses. Below is the code I am using to add rules, I am doing my best to research how to update the existing rules Remote Addresses, but with no luck.

感谢任何帮助！

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);

推荐答案

以下代码对我有用:

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
