如何修复 VPN（ipsec+ikev2）连接失败？

使用证书进行身份验证

ubuntu 16.04 + strongswan。

客户端从 win7 连接，证书已添加，如 strongswan Wiki 中所述。

配置也像在 strongswan wiki 中一样，但我收到错误：'plutostart 已弃用，因此我将其删除。

所以我的ipsec.conf：

config setup
     #plutostart=no

conn win7
     left=%defaultroute
     leftcert=vpnHostCert.der
     leftsubnet=0.0.0.0/0
     right=%any
     rightsendcert=never
     rightsourceip=10.42.42.0/24,2002:25f7:7489:3::/112
     keyexchange=ikev2
     auto=add
