Cisco ASA 之 Easy 虛擬專用網

具體原理及參數能夠參考：http://www.javashuo.com/article/p-udgdcfqf-kk.html
這裏我就不詳細說明了，大體原理都同樣，我就直接開整了
一、環境以下：

二、開始配置（自行配置接口IP）
ASA 配置以下：

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表明0.0.0.0 
# ASA中的AAA默認開啓，因此不須要手動開啓了 
ciscoasa(config)# username zhangsan password 123123               # 配置AAA認證用戶
ciscoasa(config)# crypto isakmp enable outside             # 開啓IKE協商功能
# 階段一：指定管理鏈接的相關參數，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          # 建立地址池
ciscoasa(config)# access-list split-acl permit ip 192.168.0.0 255.255.255.0 any       # 編寫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                 # 應用所建立的地址池
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            # 配置組密鑰
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            # 應用到接口

三、驗證
