具体原理及参数可以参考：https://blog.51cto.com/14227204/2449696这里我就不详细说明了，大致原理都一样，我就直接开整了1、环境如下：2、开始配置（自行配置接口IP）ASA 配置如下：
ciscoasa> en Password: ciscoasa# conf t ciscoasa(config)# int e 0/0 ciscoasa(config-if)# nameif inside INFO: Security level for "inside" set to 100 by default. ciscoasa(config-if)# ip add 192.168.0.1 ciscoasa(config-if)# no shutdown ciscoasa(config-if)# exit ciscoasa(config)# int e 0/1 ciscoasa(config-if)# nameif outside INFO: Security level for "outside" set to 0 by default. ciscoasa(config-if)# ip add 200.0.0.2 ciscoasa(config-if)# no shutdown ciscoasa(config)# route outside 0 0 200.0.0.1 # 0代表0.0.0.0 # ASA中的AAA默认开启，所以不需要手动开启了 ciscoasa(config)# username zhangsan password 123123 # 配置AAA认证用户 ciscoasa(config)# crypto isakmp enable outside # 开启IKE协商功能 # 阶段一：指定管理连接的相关参数，加密算法等 ciscoasa(config)# crypto isakmp policy 10 ciscoasa(config-isakmp-policy)# encryption 3des ciscoasa(config-isakmp-policy)# hash sha ciscoasa(config-isakmp-policy)# authentication pre-share ciscoasa(config-isakmp-policy)# group 2 ciscoasa(config-isakmp-policy)# exit ciscoasa(config)# ip local pool test-pool 192.168.1.200-192.168.1.210 # 创建地址池 ciscoasa(config)# access-list split-acl permit ip 192.168.0.0 255.255.255.0 any # 编写ACl ciscoasa(config)# group-policy test-group internal ciscoasa(config)# group-policy test-group attributes ciscoasa(config-group-policy)# split-tunnel-policy tunnelspecified ciscoasa(config-group-policy)# split-tunnel-network-list value split-acl ciscoasa(config-group-policy)# exit ciscoasa(config)# tunnel-group test1-group type ipsec-ra ciscoasa(config)# tunnel-group test1-group general-attributes ciscoasa(config-tunnel-general)# address-pool test-pool # 应用所创建的地址池 ciscoasa(config-tunnel-general)# default-group-policy test-group ciscoasa(config-tunnel-general)# exit ciscoasa(config)# tunnel-group test1-group ipsec-attributes ciscoasa(config-tunnel-ipsec)# pre-shared-key 321321 # 配置组密钥 ciscoasa(config-tunnel-ipsec)# exit ciscoasa(config)# crypto ipsec transform-set test-set esp-3des esp-sha-hmac ciscoasa(config)# crypto dynamic-map test-dymap 1 set transform-set test-set ciscoasa(config)# crypto map test-stamap 1000 ipsec-isakmp dynamic test-dymap ciscoasa(config)# crypto map test-stamap int outside # 应用到接口
