一．要求
1）R1只允许WG登录，WG能ping通Server1和Client1
2）YF和CW之间不能互通，但都可以和WG互通
3）YF可以访问Client1
4）CW不能访问Client1
5）YF和CW只能访问Server1的WWW服务
6）只有WG才能访问Server1的所有服务
二．拓扑图
三．配置
WG：IP 192.168.1.1/24 网关192.168.1.254
YF： IP 192.168.2.1/24 网关192.168.2.254
CW：IP 192.168.3.1/24 网关192.168.3.254
server1：IP 192.168.4.1/24 网关192.168.4.254
Client1: IP192.168.10.1/24 网关192.168.10.254

四．验证
YF成功访问server1 的www服务
YF ping访问server1 失败
YF ping访问Client1成功
YF ping访问WG成功
YF ping访问CW失败
CW ping访问WG成功
CW ping访问YF失败
CW ping访问server1失败
acl访问控制列表，匹配感兴趣的数据，与相应的工具对数据进行处理，本次与traffic-filter流量过滤一起，对相应的流量数据进行限制或者放行。
