防火墙虚拟系统实验

拓扑图

需求一

安全策略要求：
1、只存在一个公网IP地址，公司内网所有部门都需要借用同一个接口访问外网
2、财务部禁止访问Internet，研发部门只有部分员工可以访问Internet，行政部门全部可以访问互联网
3、为三个部门的虚拟系统分配相同的资源类

基础配置

启用虚拟系统
[FW]vsys enable 
配置资源类
[FW]resource-class r1---创建资源类r1
[FW-resource-class-r1]resource-item-limit bandwidth 2 outbound 
[FW-resource-class-r1]resource-item-limit session reserved-number 500 maximum 1000
[FW-resource-class-r1]resource-item-limit user reserved-number 100
[FW]display resource global-resource------查看剩余公共资源

创建虚拟系统
[FW]vsys name vsysa ---创建虚拟系统，名称为vsysa
[FW-vsys-vsysa]assign resource-class r1 ---设定使用的资源类
[FW-vsys-vsysa]assign interface GigabitEthernet 1/0/1 ---将接口划入虚拟系统

管理员配置
[FW]switch vsys vsysa ---切换到vsysa系统中
[FW-vsysa]aaa
[FW-vsysa-aaa]manager-user admin@@vsysa ---创建vsysa虚拟系统管理员，@@为固定，前为用户名，后为虚拟系统名称
[FW-vsysa-aaa-manager-user-admin@@vsysa]password --配置密码，需要输入两遍，密码没有回显
Enter Password:admin@123
Confirm Password:admin@123
[FW-vsysa-aaa-manager-user-admin@@vsysa]level 15 --设定权限
[FW-vsysa-aaa-manager-user-admin@@vsysa]service-type web telnet ssh ---设定登录服务，一般选择ssh和web即可
[FW-vsysa-aaa-manager-user-admin@@vsysa]quit
[FW-vsysa-aaa]bind manager-user admin@@vsysa role system-admin ---定义admin@@vsysa用户为系统管理员
