支持我们

完整性要求

  • 我保证阅读了文档，了解所有我编写的配置文件项的含义，而不是大量堆砌看似有用的选项或默认值。
  • 我保证提供了可以在本地重现该问题的服务器、客户端配置文件与流程，而不是一个脱敏的复杂客户端配置文件。
  • 我保证提供了可用于重现我报告的错误的最简配置，而不是依赖远程服务器、TUN、图形界面客户端或者其他闭源软件。
  • 我保证提供了完整的配置文件与日志，而不是出于对自身智力的自信而仅提供了部分认为有用的部分。

OpenWrt 并没有给本机配置 IPv6 路由，你还需要手动指定 IP 地址： https://sing-box.sagernet.org/configuration/shared/dial/#inet6_bind_address

手动指定ip后确实可以访问了，但如果是没配置路由的话，那么指定telecom和unicom后应该都是network is unreachable，而现在telecom不指定ip也能访问。从日志上看，初始化的时候获取了pppoe-wan接口对应的ip（？），bind_interface自动获取并设置出口ip是否更合理？

发送你的这条命令的结果：

你能再提供命令 ip addr 的结果吗？
