防火墙安全策略配置课堂实验
一.实验拓扑图

二.要求
1、VLAN 2属于办公区;VLAN 3属于生产区
2、办公区PC在工作时间(周一至周五,早8到晚6)可以正常访问OA Server,其他时间不允许
3、办公区c司以在任意时刻访问Web Server
4、生产区PC可以在住意时刻访问OA Server,但是不能访问Web Server
5、特例:生产区PC3可以在每周一早10到早11访问Web Server,用来更新企业最新产品信息
三.配置
pc1
pc2
pc3
OA

web

lsw1(trust)
vlan batch 2 3 创建VLAN
PC1 接入端口 (VLAN2 办公区)
interface Ethernet0/0/1
port link-type access
port default vlan 2
PC2 接入端口 (VLAN3 生产区)
interface Ethernet0/0/2
port link-type access
port default vlan 3
PC3 接入端口 (VLAN3 生产区)
interface Ethernet0/0/3
port link-type access
port default vlan 3
上联防火墙接口 (Trunk)
interface GigabitEthernet0/0/1
port link-type trunk
port trunk allow-pass vlan 2 3


lsw2(dmz)
vlan batch 10 创建VLAN
OA 接入端口
interface Ethernet0/0/1
port link-type access
port default vlan 10
Web 接入端口
interface Ethernet0/0/2
port link-type access
port default vlan 10
上联防火墙接口 (Access)
interface GigabitEthernet0/0/1
port link-type access
port default vlan 10


接口IP配置(Web界面或命令行)
int g0/0/0
ip address 192.168.1.126 255.255.255.0
service-manage enable
service-manage https permit
service-manage ping permit
in g1/0/1
ip address 192.168.1.254 255.255.255.0
int g1/0/2
ip address 10.0.0.254 255.255.255.0
(忘截图了)
增加安全区域
firewall zone trust
add interface GigabitEthernet1/0/1
firewall zone dmz
add interface GigabitEthernet1/0/2
firewall zone untrust
add interface GigabitEthernet0/0/0
配置安全策略
办公区(PC1) 工作时间访问OA Server
time-range work-time 08:00:00 to 18:00:00 working-day
security-policy
rule name Office_to_OA_worktime
source-zone trust
destination-zone dmz
source-address 192.168.1.1 mask 255.255.255.255
destination-address 10.0.0.1 mask 255.255.255.255
time-range work-time
action permit
办公区(PC1) 任意时间访问Web Server
rule name Office_to_Web_anytime
source-zone trust
destination-zone dmz
source-address 192.168.1.1 mask 255.255.255.255
destination-address 10.0.0.2 mask 255.255.255.255
action permit

生产区(PC2/PC3) 任意时间访问OA Server
rule name Production_to_OA
source-zone trust
destination-zone dmz
source-address 192.168.1.129 mask 255.255.255.255
source-address 192.168.1.130 mask 255.255.255.255
destination-address 10.0.0.1 mask 255.255.255.255
action permit

生产区默认禁止访问Web Server
rule name Production_to_Web_deny
source-zone trust
destination-zone dmz
source-address 192.168.1.128 mask 255.255.255.128
destination-address 10.0.0.2 mask 255.255.255.255
action deny

特例 PC3 周一 10:00-11:00 访问Web Server
time-range special-time 10:00 to 11:00 Mon
rule name PC3_Web_special
source-zone trust
destination-zone dmz
source-address 192.168.1.130 mask 255.255.255.255
destination-address 10.0.0.2 mask 255.255.255.255
time-range special-time
action permit

四.结果测试
办公区工作时间访问OAPC1 ping 10.0.0.1通
办公区任意时间访问WebPC1 ping 10.0.0.2通

生产区访问OAPC2 ping 10.0.0.1通

生产区访问WebPC2 ping 10.0.0.2不通
