    这是一个创建于 2351 天前的主题,其中的信息可能已经有所发展或是发生改变。
    VPN 已正常连接,但不知道怎么设置路由,将所有流量转到 vpn。

    ip route add 108.61.126.150 dev ppp0
    curl http://y1.511401.com/IP.php
    这样设置后,访问 y1.511401.com 是通过 vpn。

    1. 加一条 destination 为 vpn 服务器地址 /32 的路由,通过本地的网关
    2. 把默认路由改到 vpn 上

    @billlee #vpn 连上的时候好像已经自动添加路由。

    修改默认路由命令是“ ip route replace default dev ppp0 ”这样吧?但是执行后就是网络不正常
