华为模拟器eNSP将防火墙配置成三层核心交换机

命令行

首先配置PC1、PC2、PC3、PC4、R1、R2、R3的接口，IP地址，掩码，网关

PC1：

PC2：

PC3：

R1:
sys
un in en
sysname R1
int e0/0/0
ip address 192.168.70.7 24
dis this
quit

R2:
sys
un in en
sysname R2
int e0/0/0
ip address 192.168.77.7 24
dis this
quit

R3:
sys
un in en
sysname R3
int e0/0/0
ip address 177.7.7.7 24
dis this
quit 

接下来配置两个交换机的接口，连接PC的那些接口设置成Access口，通往防火墙的接口设置成Trunk口，以及创建vlan区并把接口划分到对应的vlan区

LSW1:
sys
un in en
sysname LSW1
vlan batch 7 17
int e0/0/2
port link-type access
port de vlan 7
dis this
int e0/0/3
port link-type access
port de vlan 7
dis this
int e0/0/4
port link-type access
port de vlan 17
quit
dis port vlan
int e0/0/1
port link-type trunk
port trunk allow-pass vlan 7 17
dis this
quit
dis port vlan

LSW2:
sys
un in en
sysname LSW2
vlan 10
int e0/0/2
port link-type access
port de vlan 10
dis this
int e0/0/1
port link-type trunk
port trunk allow-pass vlan 10
dis this
quit
dis port vlan

在防火墙上创建vlan，接着对防火墙上的接口进行设置配置，GE 1/0/0、GE 1/0/1口配置成Trunk口，GE 1/0/2、GE 1/0/3配置成Access口并允许对应vlan通过，然后新建逻辑接口并分入对应的vlan

FW:
sys
un in en
vlan batch 7 10 17 70 77
dis port vlan
int g1/0/0
portswitch
port link-type trunk
port trunk allow-pass vlan 7 17
dis this
int g1/0/1
portswitch
port link-type trunk
port trunk allow-pass vlan 10
dis this
int g1/0/2
portswitch
port link-type access
port de vlan 70
dis this
int g1/0/3
portswitch
port link-type access
port de vlan 77
dis this
quit
dis ip int brief
interface vlanif 7
ip address 192.168.7.1 24
service-manage ping permit
dis this
quit
interface vlanif 10
ip address 192.168.10.1 24
service-manage ping permit
dis this
quit
interface vlanif 17
ip address 192.168.17.1 24
service-manage ping permit
dis this
quit
interface vlanif 70
ip address 192.168.70.1 24
service-manage ping permit
dis this
quit
interface vlanif 77
ip address 192.168.70.1 24
service-manage ping permit
dis this
quit
dis port vlan

把每个vlan都建立对应的区域，并把对应的逻辑接口划分到对应的区域，以实现精细化管控

FW:
sys
firewall zone name vlan7
set priority 75
add int Vlanif7
dis this
quit
firewall zone name vlan10
set priority 77
add int Vlanif10
dis this
quit
firewall zone name vlan17
set priority 76
add int Vlanif17
dis this
quit
firewall zone name vlan70
set priority 78
add int Vlanif70
dis this
quit
firewall zone name vlan77
set priority 79
add int Vlanif77
dis this
quit

配置到这里，每个vlan的PC就可以访问各自的网关了，验证结果如下：
vlan7-PC1:

vlan17-PC3:

vlan10-PC4:

vlan70-R1:

vlan77-R2:

相同区域可以访问，不同区域不能访问，验证结果如下：

接下来只需要对不同区域设置对应需求的安全策略即可实现精细化管控

FW;
sys
security-policy
rule name vlan7_to_vlan17
source-zone vlan7
destination-zone vlan17
service icmp
action permit
dis this

验证结果如下：

其他的就不演示了，不同区域的设置对应的安全策略即可实现精细化管控

如果是内网的PC想要访问外网的地址，做个NAT源地址转换，做个策略，再在外网口上设置一条缺省路由即可

FW:
sys
firewall zone trust
add int g1/0/0
add int g1/0/1
add int g1/0/2
add int g1/0/3
dis this
quit
firewall zone untrust
add int g1/0/4
dis this
quit
int g1/0/4
ip address 177.7.7.1 24
dis this
quit
ip route-static 0.0.0.0 0 177.7.7.7
nat-policy
rule bane vlan7_nat_untrust
source-zone vlan7
egress-int g1/0/4
action nat easy-ip
dis this
quit
quit

验证结果：
