OpenWrt 是一个专门面向嵌入式设备的 Linux 发行版。你可以将 OpenWrt 支持的型号的嵌入式设备，比如各种路由器上的系统，换成一个有更多可能性可以折腾的 Linux 系统。 OpenWrt 官方网站
这是一个创建于 878 天前的主题，其中的信息可能已经有所发展或是发生改变。
我在 OpenWRT 上安装了 tailscale ，并且开启了 IPV6 ，但是发现还是无法直连，总是通过 DERP 来中继。
我尝试着放行 IPV6 防火墙的 41641/udp ，发现还是一样。
以下是我的防火墙规则 Traffic Rules：

已配置完成，使用默认教程安装完其实就会自动直连了。
