    调整后依然不行，服务器上执行wg，能看到连接，但是网络不通，两个客户端都不通，单独一个客户端也不行

    client 的 privatekey 要自己生成，不要和 server 的 key 相同

    你客户端和服务端用了相同的一对密钥，我没见过这样的配置，要不用两对试试看，即服务端配置文件用私钥 A 和公钥 B，客户端配置文件用私钥 B 和公钥 A

    楼主，你从客户端 tracert 的时候中间路程都是* * *吗，我设置的除了开头和最后一跳有显示，其他都是显示* * *，想不出是什么原因。。

    @zro 其实我还没有通，我 wg 状态都显示两台终端了，但是网络没有互通，这个目前日志也不成熟，可能要放弃这个工具

    刚开始看别人的 WG 配置也是云里雾里的，但现在配多几次感觉很好用~

    我发现你的配置有个问题，客户端的 AllowedIPs = 10.0.1.0/22，其实是等价 10.0.0.0/22 的。。

    另外可能要配合 ip route 命令来查互通不了的问题~

    盲猜你客户端没有加路由信息。

    你的客户端 是运行在哪里的？
    需要进入其网络配置端口，添加路由信息，即把所有流量全部路由到 wireguard 的虚拟网卡上

    @SteveRogers 客户端 AllowedIPs 改成 0.0.0.0/0，那个配置是用来决定哪些流量发往服务端的

    @zro 复制铁站的，肯定不会手工输滴


    @bitdust 这个客户端有两个 一个是手机、一个是电脑，没有单独加路由，需要怎么加呢
    @301 这个也尝试过，客户端 peer 允许 0.0.0.0/0,不行，用路由跟踪，全部都是*，并且不可达

    @301 那我用 docker 试试，估计群晖的套件问题了

    server 以及每个客户端自带一“对” key，本质就是交换 public key 进行 end to end 验证
