如何从 ubuntu box 连接到 AWS Client VPN？

Question

我使用本指南创建了 aws vpn 客户端端点。现在我想从我的 ubuntu 盒子连接到这个 vpn 端点。

为此，我已经下载了客户端证书并使用本指南使用 TLS 身份验证方法连接到 vpn。

但是当我尝试从我的网络管理器连接到 VPN 时，我超时了。

注意：我已经为我的系统打开了所有 UDP 流量。

下面是 syslog 的输出。请让我知道出了什么问题。

创建客户端 VPN 终端节点后，控制台会显示 DNS 名称，例如“\n cvpn-endpoint-0102bc4c2e49f1e44.prod.clientvpn.us-west-2.amazonaws.com”。当您需要指定 DNS 名称时，必须在显示的名称前面指定一个随机字符串，格式为 \xe2\x80\x9c[随机字符串]。显示的 DNS 名称，例如 \xe2 \x80\x9casdfa.cvpnendpoint-0102bc4c2e49f1e44.prod.clientvpn.us-west-2.amazonaws.com”。
