VPN ipsec 策略再web页面配置生成后，还需配置其他的么? acl自动生成了。

如果和对端不通，要如何测试问题原因？

display ike sa

display ipsec sa

看看这两个的状态是否正常，确认是协商到第一还是第二阶段没有起来；

可以看下案例分析http://kms2.h3c.com/Search.aspx?keyword=ipsec

1. 首先检查两端设备是否可以相互ping通，保证两端设备通信正常。 2. 检查两端设备配置是否一致，主要从感兴趣流、预共享密钥确认一致、ike算法确认一致。 3. 确认下两端设备出接口上是否有NAT业务，如果有NAT业务的话，流量会先匹配NAT模块走掉而不匹配IPSec，所以需要在NAT的acl中先配置rule deny掉感兴趣流。对于V5平台的设备就方便得多，可以在外网口配置ipsec no-nat-process enable这个命令来实现。
