用强天鹅配置vpn

Question

我需要做一个vpn站点到站点，公司的整合给了我这些对撞机.

网关: 41.xxx.xx.xx

主机IP : 41.xxx.x.xx端口xxxx

转换集: esp-aes-256 esp-md5-hmac

预共享密钥：

我配置了Strongswan http://www.strongswan.org。但不幸的是，我没能让它开始工作。

以前有人这样做过吗？谢谢。

您应该提供由StrongSwan服务器生成的日志，以便人们可以帮助您。下面是如何找到与问题相关的日志：

1. 启动VPN服务器使用: sudo ipsec启动
2. 一旦VPN服务器运行，请在终端中键入以下命令，以查看计算机上发生了什么: sudo -f /var/log/syslog --该命令允许您在登录到syslog时看到终端上的事件。
3. 现在尝试从VPN客户端连接。如果客户端能够到达服务器，您将看到在syslog中charon进程下记录的事件。如果您没有看到任何与charon相关的信息，这很可能是一个网络连接问题。
4. 还可以使用sudo tail -x /var/log/syslog > debugfile将syslog的最后一行x转储到debugfile以进行更好的分析。
5. 如果您无法识别问题，请在此张贴这些日志。
