问题描述

我想创建一个用于数据包筛选的防火墙.

当用户访问一个他不应该访问的网站时，我的应用程序应该捕获该请求并在浏览器中显示一个自定义html页面，表明他无法访问该网站.

因此，如何捕获和丢弃或阻止数据包并显示自定义HTML.

问候，

Hi,

I want to create a firewall for packet filtering.

When user accesses a website which he is not supposed to, then my application should trap the request and display a custom html page in the browser, displaying that he cannot access the website.

So how can I trap and drops or block the packet and display custom HTML.

Regards,
Wasim Shaikh

推荐答案

您为什么要重新发明轮子，因为这些机器是Intranet的一部分，因此实现了代理服务器来控制Internet访问，然后将其用于Windows和Mac计算机，并且不需要安装可以在客户端计算机上关闭/绕过的实用程序.

Why are you trying to reinvent the wheel, as the machines are part of an Intranet implement a proxy server to control internet access this will then work for windows and Mac machines and not require installation of utilities that could be shut-down/bypassed on the client machines.
