IPSec要左右2边的router match上了,才能up,才能左右互ping,不然配置里会说要等
另一边搭上了才行。
IPSec要看3点。
access-list的 private IP有没有对上,
crypto的 WAN IP对上,WAN能不能互相ping,
然后才是crypto-map。

你的问题是traffic go through 某个中心center,then,
check center的nonat 部分,要把B点也nonat了,B点就行了。 |

initiated by A can be established (so will be IPsec SA), but if there is no
traffic and IPsec SA times out and then B tries to initiate, ISAKMP request
will be dropped by A side's firewall.
