我需要做一个站点到站点的 vpn，要集成的公司给了我这些参数。
网关：41.xxx.xx.xx
主机 IP ：41.xxx.x.xx 端口 xxxx
变换集：esp-aes-256 esp-md5-hmac
预共享密钥：xxxxxxxxxxxxxxxxxxxx
我已经配置了 Strongswanhttp://www.strongswan.org. 但不幸的是我无法让它工作。
有人做过这个吗？谢谢。
已编辑..............................................这是我的 auth.log

您应该提供 StrongSwan 服务器生成的日志，以便人们能够帮助您。以下是查找与您的问题相关的日志的方法：
使用以下方式启动 VPN 服务器：
sudo ipsec startVPN 服务器运行后，在终端中输入以下命令，查看机器上发生的情况：
sudo tail -f /var/log/syslog此命令可让您在终端上看到正在记录到系统日志中的事件。
现在尝试从 VPN 客户端连接。如果客户端可以访问服务器，您将看到正在处理
syslog下记录的事件charon。如果您看不到与 相关的任何内容charon，则很可能是网络连接问题。您还可以
sudo tail -x /var/log/syslog > debugfile转储x系统日志的最后几行，以便debugfile更好地进行分析如果您无法识别问题，请在此处发布这些日志。
