    例如: www.gentoo.org, 可以 ping 通, dig 命令可以正常解析 dns, 但是不能访问.
    这就是所谓的被墙吗?

    墙到底做了什么使得网站不能访问呢?求科普.

    @Mutoo 谢谢, 这个网页可以获得信息说明了该网站没有被墙? 请问无法登录该网站可能出于什么样的原因呢?

    很简单，翻墙过去，能访问就说明被强了。

    至于墙做了什么，就要从TCP/IP 协议讲起。。。。

    @lch21 我测试了 ping, dns 解析, traceroute 全都正常... 翻墙可以访问地说..

    gentoo.org 都会被墙, 这是什么违反什么规定了.....没道理阿..
