vpn配置好之后，安卓手机无法使用该vpn（ios可以正常使用），根据观察到的日志来看与ios使用的加密方法是不一样的。
- 安卓：AES_256-HMAC_SHA2_256
- ios：AES_256-HMAC_SHA1
- 不过感觉这个加密方法可能是自动检测匹配的？说不清楚后面需要配置一下ipsec的加密方法来重新测试一样，同时啊表示应该同时配置一下ipsec vpn
- 还有一个可能是安卓没有采用标准的认证方式链接 ↓
- Comment 203 from strawman is particularly interesting as the person identified the bug and provides a fix. Basically, Google is not following the RFC by the book and OpenSwan doesn’t tolerate this error. The user fixed the building of the ISAKMP NAT-OA packet (byte 7) in /system/bin/racoon and uploaded his patch.
