防火墙虚拟系统实验

实验拓扑

二.实验需求

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

三 配置

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   -设定使用的资源类

管理员配置

[FW]switch vsys vsysa 切换到vsysa系统中
<FW-vsysa>sys
Enter system view, return user view with Ctrl+Z.
[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
 
Enter Password:
 
Confirm Password:
[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
Warning: The user access modes include Telnet or FTP, so security risks exist.
[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
 

创建安全策略和NAT策略

[FW]security-policy 	
[FW-policy-security]rule name to_internet
[FW-policy-security-rule-to_internet]source-zone trust
[FW-policy-security-rule-to_internet]destination-zone
[FW-policy-security-rule-to_internet]destination-zone untrust
[FW-policy-security-rule-to_internet]access-authentication
[FW-policy-security-rule-to_internet]action permit
[FW-policy-security-rule-to_internet]q
[FW-policy-security]q
[FW]nat-policy 
[FW-policy-nat]rule name nat1
[FW-policy-nat-rule-nat1]source-zone trust
[FW-policy-nat-rule-nat1]egress-interface GigabitEthernet 1/0/0
[FW-policy-nat-rule-nat1]source-zone 
[FW-policy-nat-rule-nat1]source-address 10.3.0.0 16

 在vsysa配置如下：

[FW]switch vsys vsysa
<FW-vsysa>sys
Enter system view, return user view with Ctrl+Z.
[FW-vsysa]int g 1/0/1
[FW-vsysa-GigabitEthernet1/0/1]ip address 10.3.0.254 24
[FW-vsysa-GigabitEthernet1/0/1]quit
[FW-vsysa]interface Virtual-Template	
[FW-vsysa]interface Virtual-if
[FW-vsysa]interface Virtual-if 1
[FW-vsysa-Virtual-if1]ip address 172.16.1.1 24
[FW-vsysa]firewall zone trust
[FW-vsysa-zone-trust]add int g 1/0/1
[FW-vsysa-zone-trust]q
[FW-vsysa]firewall zone untrust	
[FW-vsysa-zone-untrust]add int Virtual-if 1
[FW-vsysa-zone-untrust]q
[FW-vsysa]ip route-static 0.0.0.0 0 public 
[FW-vsysa]ip address-set ip_add01 type object 
[FW-vsysa-object-address-set-ip_add01]address range 10.3.0.1 10.3.0.10
[FW-vsysa-object-address-set-ip_add01]q	
[FW-vsysa]security-policy
[FW-vsysa-policy-security-rule-to_internet]source-zone trust 
[FW-vsysa-policy-security-rule-to_internet]destination-zone untrust
[FW-vsysa-policy-security-rule-to_internet]source-zone 
[FW-vsysa-policy-security-rule-to_internet]source-address address-set ip_add01
[FW-vsysa-policy-security-rule-to_internet]action permit

 在vsysb配置如下

[FW]switch vsys vsysb
<FW-vsysb>sys
Enter system view, return user view with Ctrl+Z.
[FW-vsysb]int g 1/0/2
