现在的ASA 版本基本上都9.X以上了，很多新特性增加了，现在去实施的出厂都不会太老的IOS，但是很多时候客户环境就是有一些之前部署的ASA，需要与之搭建VPN ，那么不同版本之间搭建IPSecVPN 怎么配置，注意哪些东西呢？ 分享一个官方案例给大家，有需要可以查阅。
第一： 配置8.25X 版本一下的ASA
crypto isakmp enable outside
crypto isakmp policy 10
authentication pre-share
encryption aes
hash sha group 2
lifetime 86400
tunnel-group 172.16.1.1 type ipsec-l2l
tunnel-group 172.16.1.1 ipsec-attributes
pre-shared-key cisco
access-list 100 extended permit ip 10.1.1.0 255.255.255.0
10.2.2.0 255.255.255.0
crypto ipsec transform-set myset esp-aes esp-sha-hmac
crypto map outside_map 20 set peer
crypto map outside_map 20 match address 100
crypto map outside_map 20 set transform-set myset
crypto map outside_map 20 set pfs
crypto map outside_map interface outside
access-list nonat line 1 extended permit ip 10.1.1.0 255.255.255.0
10.2.2.0 255.255.255.0
nat (inside) 0 access-list nonat
第二 9.X版本的ASA 配置
crypto ikev1 enable outside
crypto ikev1 policy 10
authentication pre-share
encryption aes
hash sha
group 2
lifetime 86400
tunnel-group 192.168.1.1 type ipsec-l2l
tunnel-group 192.168.1.1 ipsec-attributes
ikev1 pre-shared-key cisco
!Note the IKEv1 keyword at the beginning of the pre-shared-key command.
