OpenVPN 桥接网关停止所有流量

我不确定这是linux还是windows的问题。我已经使用包含 tap0 和 eth0 的桥接接口设置了 openvpn。我的客户端计算机（win10）通过 dhcp 服务器获取其 IP。配置行server-bridge会导致 dhcp 网关被删除，因此客户端不会收到它。当我将该行更改为server-bridge nogw网关地址时，会提供给客户端，但我无法 ping 或连接到网关。我有什么错吗？

当我让它正常工作并通过 VPN 路由流量时，以下行将添加到路由表中：

0.0.0.0     0.0.0.0       172.16.0.1  172.16.1.205 2
64.191.11.0 255.255.255.0 192.168.1.1 192.168.1.96 61

第二行允许 VPN 流量使用原始网关。

OpenVPN 服务器配置文件

添加nogw到server-bridge线路允许网关通过 dhcp，但我无法再访问服务器。脚本up并将downTap 接口添加到桥或将其删除。

OpenVPN 客户端配置：
