两端接口都配置了 nat outbound , ipsec apply policy 1 , ipsec no-nat-process enable
《r3》 有出口IP的

麻烦大神帮忙看看什么问题
acl内容感兴趣流发一下
r1这侧是原192.168.1.0目的172.16.0.0 r3侧是原172.16.0.0 目的192.168.1.0
acl advanced 3000 rule 0 permit ip source 172.16.0.0 0.0.0.255 destination 192.168.1.0 0.0.0.255 acl advanced 3000 rule 0 permit ip source 192.168.1.0 0.0.0.255 destination 172.16.0.0 0.0.0.255 acl advanced 3000 rule 0 permit ip source 192.168.1.0 0.0.0.255 destination 172.16.0.0 0.0.0.255
换了nat outbound 3100 拒绝流了,也不行
您好,第二阶段是ipsec 阶段
起不来看一下双方的加密算法协商是否一致
其次就是debugging IPSec
提示找不到隧道
Can't find block-flow node.The reason of dropping packet is no available IPsec tunnel.
这是r3的 Received DNS analyse invalid result or have no address result.
提示找不到隧道
策略需要在接口下应用,你配置了吗
这2个地方应该要一致,接口下应用的策略名和你配置都不一样
我调用的策略模版,野蛮模式就得这么配的
interface GigabitEthernet0/0 port link-mode route combo enable copper ip address dhcp-alloc nat outbound 3100 ipsec apply policy 1
肯定调用了啊
找到问题了,就是你这个截图里对端IP是没有的,我填的remote-address AAA,我把这个删了就通了
STRING<1-253> Host name of the remote peer 它这个提示对端主机名应该也是能填的,不清楚为啥删了就通了= =
我调用的策略模版,野蛮模式就得这么配的
用这种 中心节点---分支节点的方式试试吧 固定ip 当中心节点,自动获取充当分支
野蛮模式配置案例:
防火墙上网配置请参考“2.3.2 防火墙外网使用固定IP地址上网配置方法”及“2.3.1 防火墙外网使用拨号上网配置方法”进行配置,本文只针对IPSEC VPN配置进行介绍。
