你把他丢 gpt 让他分析，他可以给你分析日志，问题，可能的原因，解决思路及方法。。。

LCP terminated by peer 是服务器中断，立马就重连上，更是说明光猫正常，就是服务器断开的。

LCP terminated by peer 联通那边主动断开的，如果之前正常，最近不正常，那就排查下，换个路由器或者直连电脑拨号，测试一天看看。
1. 拨号的账号密码再核对一下。联通各省在回收公网 ipv4 ，以前是[帐号 @lan]拨号获得公网，现在不行了，去掉 @lan 正常拨号。
2. 光猫如果是自己换的，没入库可能被踢下线。现象也是这样，拨号之后检查终端，未入库断开拨号。

@kkk9 #3 我没有公网 IP ，拨号的账号密码都是对的，光猫也是联通给的，自己没换过，路由器的话，R2S 的固件也是一年多没有刷过没有动过了，真的是很奇怪
