2. 使用命令show conn detail查看Conn表
3. 查看ASA和AR【R1】的路由表

4. 配置ACL禁止Client3訪問Sever2
   實驗步驟：

   1. 配置ASA及路由器：
      R1：配置IP地址：interface GigabitEthernet0/0/0
      ip address 192.168.1.1 255.255.255.0
      interface GigabitEthernet0/0/1
      ip address 10.1.1.254 255.255.255.0
      interface GigabitEthernet0/0/2
      ip address 10.2.2.254 255.255.255.0
      
      配置下一跳: ip route-static 0.0.0.0 0.0.0.0 192.168.1.254

   2. 配置ASA及端口：
      ASA：配置接口:
      interface GigabitEthernet0
      nameif inside
      security-level 100\inside默認安全級別為100
      ip address 192.168.1.254 255.255.255.0
      interface GigabitEthernet1
      nameif outside
      security-level 0\outside默認安全級別為0
      ip address 192.168.8.254 255.255.255.0

        interface GigabitEthernet2
        nameif DMZ
        security-level 50\\DMZ默認安全級別為0-100之間即可
        ip address 192.168.3.254 255.255.255.0
      route inside 10.1.1.0 255.255.255.0 192.168.1.1 1\\配置下一跳
       
      

      route inside 10.2.2.0 255.255.255.0 192.168.1.1 1\配置下一跳

3. 配置ACL：ASA(config)# show ru access-list
   access-list ICMP extended permit icmp any any \設置ping包成功【ping為ICMP】
   access-list in-to-out extended deny ip 10.1.1.0 255.255.255.0 any
   access-list in-to-out extended permit ip any any
   access-list DMZ extended permit tcp host 192.168.8.1 host 192.168.3.100
   
   access-list C3-S2 extended deny tcp host 192.168.3.1 host 192.168.8.100
   access-list C3-S2 extended deny tcp host 192.168.3.1 host 192.168.8.100
4. 調用ACL：access-group C3-S2 in interface outside
   access-group DMZ in interface outside
   實驗結果：
   使用命令show conn detail查看Conn表
   
   查看ASA的路由表
   
   DMZ發布Web服務器，Client2可以訪問Server3
   
   配置ACL禁止Client3訪問Server2
   
   
   查看AR【R1】路由表
   
   謝謝大家支持
