环境为家庭带宽（联通、电信都有）300-500M共30条，每条线下挂10-20台机器，日常下载比较多，网络基本占满，现象是外网频繁重拨。经查看日志，发现为ikuai软路由器由于20次回声请求未获回应，主动断开重拨。在ikuai系统中没有找到相应配置可以优化，咨询ikuai客服为目标没有现成解决方案。建议向产品需求建议反馈。

解决思路
1，增加回声请求配置，允许手动调整，比如200个回声请求无回应再主动断开重拨，以使主动断开重拨次数减少；
2，增加关闭回声请求配置，比如用有没有流量发生来检测链路状态等来更具健壮性的策略来判断重拨机制；

请问是否解决呢，我现在最快1分钟，最多1 小时就会自动断网。

有时候一天几次 有时候几天一次。。。但是断开了一半要1.2分钟才能拨

楼主说的 检测没有流量 这个机制已经内置。 PPPoE pptp L2TP  在LCP 检测失败的前提是 流量没有变化时，才会判断它真的是断线。该功能应该是在 3.1.x 版本实现。
