移动宽带某终端设备 | 然后内网 web 就连不上的问题

前几天移动客服给我电话安利我免费装他们的“宽带机顶盒”，当时忙（也是好奇）就答应来装了。

装好后一看 原来是两个设备，一个是把原来的光猫整合到一个貌似路由器的设备（铭牌上是“***无源光纤接入用户端设备”，自带一个 wifi AP ）里；另一个是带 Dolby 的“***网络机顶盒”。

然后问题来了，突然发现我内网机器上的 web 页面都打不开了，我自己的路由器（ 192.168.10.1 ）管理页面打不开，Rpi 上的 Transmission UI 也打不开，连 移动那破“用户端设备”上的配置 web 页面 192.168.1.1 也打不开。表现是：重连几次后，就报 reset （就像被墙了一样惹）。

现在内网的拓扑如下：

                                              ------------------我自己的路由器 

                                                                               |           |             | 

                                                                          电脑     RPi        ....

我已反复检查自己机器的防火墙（都是关着的），Transmission 的白名单也是关闭的。

暂时拔掉“网络机顶盒”，nmap 扫一扫，发现：192.168.1.0/24 这个域竟然有三个 IP 地址（ 1,2,3)。-sS 显示如下：

厉害了！不知移动这是要干啥~~（开辣么多 interface ）

有大佬可以来解读一下么？

以及我遇到的这问题到底是不是跟移动这破终端有关？有哪些可能的原因呢？
