Secure 第四天作业
实验需求：
- 需求一拓扑：
按照以上拓扑所示，完成以下需求：
- 参考以上拓扑，配置设备IP地址，使用UNL里Secure第四天拓扑即可。（有兴趣的同学课后也可按照PPT原拓扑做做实验）；
- 配置Zone-Base Policy Firewall，Zone Nname为Inside/Outside，并配置VRF，名字为QYT，监控Inbound的ICMP/Telnet流量；
- 内部地址10.1.1.1静态一对一转换到外部地址202.100.1.101；
- 配置User-Base FW，Username=user1，Group=group1，监控PC去往10.1.1.1的HTTP流量；
- 配置Radius，在满足需求4的同时，Reset掉uri中的“who”关键字。
设备配置：
1） 参考以上拓 ，配置设备 IP 地址，使用 UNL 里 Secure 第四 扑即可。

parameter-map type regex who
pattern [Ww][Hh][Oo]
class-map type inspect http match-all user1-http
match request uri regex who
!
policy-map type inspect out-in
class type inspect out-in-http
