我的 OpenVPN 客户端（版本 2.5.5）不知为何无法设置默认路由。
路由完全由客户端 ovpn 文件：
route-gateway 10.24.0.1
route 152.66.182.241 255.255.255.255 net_gateway
route 192.168.24.0 255.255.255.0
route 192.168.0.0 255.255.0.0 net_gateway
route 10.24.0.0 255.255.0.0
route 10.0.0.0 255.0.0.0 net_gateway
route 0.0.0.0 0.0.0.0
但是，我看到openvpn 输出：
$ sudo openvpn my-file.ovpn

因此，我的流量不会通过我的 VPN。但是，当我强制使用 tun0 接口（例如使用 ping -I tun0）时，VPN 工作正常。我可能会错过什么？
