VB怎样绕过防火墙连接网络？期待高手解答

绕过防火墙的话是很难做到的，至少我没有这个能力。因为这个要取得系统的优先权限，相信VB也很难做到这一点。如果是系统防火墙的话，你可以用关闭系统防火墙服务的方法来实现： shell "cmd net stop sharedacc" '这个是关闭系统防火墙的命令，相反，如果要打开一个系统服务的话你可以把net stop改为net start. 另外是我收集的一些其它防火墙的服务名称，你可以用上述方法对其进行关闭，你也可以把下面的命令保存成为一个批处理文件（*.bat）执行： net stop "Alerter" /y

用VB6.0或VB.NET或C#做一个客户端，用来“限制用户只能在办公室访问Web系统”

两种方法

1、将防火墙设置为仅内部访问，不过很多内部的功能将不能使用

2、在服务器端写一个IP锁定的功能，凡IP符合就能使用，不符合就不能使用，这样方便你将来给某些外部的机器开绿灯
