我正在尝试创建 OpenVPN 连接。我使用 Windows 的同事收到了一个自解压可执行文件，可以设置所有内容，但我可以.ovpn从他们的配置中恢复 和 密钥文件。
.opvn 说：
dev tun
persist-tun
persist-key
cipher AES-256-CBC
auth SHA1
tls-client
client
resolv-retry infinite
remote aaa.bbb.ccc.ddd 1194 udp
verify-x509-name "Bad_VPN" name
auth-user-pass
pkcs12 SomeKey.p12
tls-auth SomeKey-tls.key 1
ns-cert-type server
comp-lzo adaptive
有了足够的密码，连接就会启动，我可以 ping 通系统。但是，如果我启动 VPN，并立即启动ping我保持运行的 VPN：
- 大约一分钟后，不再有任何 ping 答案（没有 seq>57）
- 大约一分钟后，我收到最后一个 ping 答案（seq=118 的一个）和一条“tun0”已停用的消息。
此外，当 VPN 启动时，我只能 ping 它连接到的网络。
当 VPN 启动时，ip route显示：
default via 192.168.30.1 dev tun0 proto static metric 50
default via xxx.143.182.1 dev wlp4s0 proto static metric 600
xxx.0.136.31 via xxx.143.182.1 dev wlp4s0 proto dhcp metric 600
xxx.143.182.0/23 dev wlp4s0 proto kernel scope link src xxx.143.182.197 metric 600

192.168.30.0/24 dev tun0 proto kernel scope link src 192.168.30.3 metric 50
作为比较，没有 VPN：
default via xxx.143.182.1 dev wlp4s0 proto static metric 600
xxx.0.136.31 via xxx.143.182.1 dev wlp4s0 proto dhcp metric 600
xxx.143.182.0/23 dev wlp4s0 proto kernel scope link src xxx.143.182.197 metric 600
（xxx.*.*.*是我常用的网络，aaa.bbb.ccc.ddd是VPN网关）。

使用 NM gui，我尝试删除自动路由，但无法通过这种方式获得有效的配置。我还尝试了几种变体，ip route del default via 192.168.30.1 dev tun0但尽管我没有看到任何错误消息，但路线仍然存在。
有什么想法（除了启动 Windows VM...）？
运行（K）ubuntu 16.04
更新：好吧，我撒谎了:)我也有 docker，并docker0从ip route输出中删除...并且使用 NM GUI 断开连接docker0似乎可以解决问题。跑了 2000 万次，只丢失了几个数据包 (10/1261)。然而，我找不到任何 OpenVPN 和 docker 不喜欢彼此的暗示。
更新“2：上述工作测试是在家中通过 PLC 在以太网上进行的。因此，它可以通过有线连接到我的简单家庭 LAN，但不适用于：
- 公司内部网络（wifi或以太网）
- 公司的“客人”wifi
- 我家的无线网络
- 我的手机（作为 Wifi 主机点）
- 我的手机（带 USB 线）
