OpenVPN需要一个关于路由选项的网关参数

我有一个没有连接到VPN服务器的OpenVPN客户端。 我粘贴下面的完整日志，但特别是，我得到这些路线的问题：

OpenVPN路由：OpenVPN需要一个–route选项的网关参数，并且没有默认由–route-gateway或–ifconfig选项指定

OpenVPN路由：无法parsing/解决主机/networking的路由：10.8.0.1

有很多客户端configuration相同的客户端连接就好了。 这个客户端（和一些其他客户端）已经连接，由于系统时间变得太不同步（我相信）而失去了连接，从而同步系统时间，但现在仍然无法连接。 通常，重新启动系统可以解决问题。 所以它似乎不是VPNconfiguration的问题，而是客户端系统的问题。

• 不同主机上的多个openvpn客户端
• OpenVPN在两个远程站点上具有相同的子网
• 给VM一个自己的IP地址
• 为什么tcpdump看到回复，但不是netcat
• 服务器重启后OpenVPN重新连接

我不太了解路线问题或解决问题。 我需要处理从时间同步问题恢复，但现在，为什么我不能从这个客户端手动启动VPN连接？ 什么会导致OpenVPN现在需要一个网关参数？
