21 Sep 2017 / Asus Merlin+Raspberry打造无感知路由

在上一篇文章《基于无预置IP list的GFW IP解锁方法》中讲述了如何通过Iptables自动检测受干扰的IP地址，在这里将进一步将相关代码整合到实际路由器中。前期个人买了一个Asus Merlin AC-87U，本想将Shadowsocks编译进路由器中，直接实现路由器内的透明代理转发，但尝试半天后，始终未能编译。于是考虑用RaspberryPi+Shadowsocks外挂AC-87U下实现路由转发。

20 Sep 2017 / 基于无预置IP list的GFW IP解锁方法

在以往的基于路由、iptables解锁GFW IP封锁的方法中，均需要一份国内或国外的IP地址列表，然后进行策略路由。基于这种方案的解锁，需要人工去维护一张IP地址列表，其中基于chnroutes方案生成的国内IP地址列表就有8000多条记录,在加载的时候会比较耗时，同时给路由器带来一定负担。本文给出一种基于无IP列表的自动IP访问监测及路由更变策略。
