OpenVPN-2.5.1-I601-amd64.msi我在电脑上安装了 OpenVPN Windows 10 Pro x64。
该服务器是 Netgear R6230 路由器，我为其配置了 DDNS 和 VPN。
问题：我的连接尝试卡在“正在连接”

如你所见，选项并不多。我下载了配置文件，这没什么问题。
这是我下载的配置文件。我将通用名称更改为唯一名称。
client
dev tap
proto udp
dev-node NETGEAR-VPN
remote <DDNSName> 12974
resolv-retry infinite
nobind
**key-direction 1**
persist-key
persist-tun
ca ca<name>.crt
cert client<name>.crt
key client<name>.key
cipher AES-128-CBC
comp-lzo
verb 5
有什么想法吗？
答案 1 的更新
我添加了缺失的键方向，请参阅上面更新的脚本，两侧都有 ** 表示方向。
日志看起来一样。以下是最后几行。

答案1
标准 openvpn 配置包含一个项 key-direction，它控制哪一方开始密钥协商（这是您的连接卡住的地方）。我在您的客户端配置文件中没有看到这个。
尝试将以下内容添加到您的客户端配置文件中：
key-direction 1
它可以放置在“客户端”标签之后的任何位置。（正如评论中指出的那样，这个标签可能没有帮助。）
此外，可能还有防火墙。R6230 说明并未指出端口 12973/upd 和 12974/udp（原始配置）或您决定使用的任何端口都必须通过防火墙转发到 R6230，OpenVPN 才能正常工作。
