 如果你想要 VPN 客户端在 VPN 连接处于活动状态时使用指定的公有 IP 作为其 "出站 IP"，并且指定的 IP **不是** Docker 主机上的主 IP（或默认路由），则可能需要额外的配置。在这种情况下，你可以尝试在 Docker 主机上添加一个 IPTables `SNAT` 规则。如果要在重启后继续有效，你可以将命令添加到 `/etc/rc.local`。

 Additional configuration may be required if you want VPN clients to use the specified public IP as their "outgoing IP" when the VPN connection is active, and the specified IP is NOT the main IP (or default route) on the Docker host. In this case, you can try adding an IPTables `SNAT` rule on the Docker host. To persist after reboot, you may add the command to `/etc/rc.local`.
