检查下两端感兴趣数据流的配置,安全策略配置

两端都是路由器,acl也没问题

有点乱啊,摘出来的内容也比较少,只能靠猜,你应该做的是gre over ipsec吧,而且是野蛮模式。


如果是想在出接口的nat中排除ipsec的感兴趣流,那么deny的条目应该写在前面,permit ip应该写在最后啊。而且后面deny的流好像也有点奇怪,建议检查一下。r1上没有路由指向隧道也挺不对劲的。


评论的图片在PC上看不到,直接做个差不多的实验给你看吧。

r1没有tun路由是我没写,acl已经将deny排前了,但是loopback接口还是不通。先通loopback接口业务才能通,所以先解决loopback通吧,评论有图片了
