[eNSP]华为防火墙基础——Local、DMZ、Trust、Untrust互联

设备清单：1台PC、2台路由器（AR2220）、1台防火墙（USG6000V）

试验拓扑：实验目的：实现trust、untrust、local、dmz区域互通。PC可以ping通R-1和R-2。

试验说明：PC在trust内、R-2在untrust内、R-1在dmz内。ip地址见拓扑。

配置开始：

R1的IP地址：

<R1>dis ip in br
Interface                         IP Address/Mask      Physical   Protocol  
GigabitEthernet0/0/0              172.16.0.1/24        up         up        
GigabitEthernet0/0/1              unassigned           down       down      
NULL0                             unassigned           up         up(s)

R2的IP地址：

<R2>dis ip in br
Interface                         IP Address/Mask      Physical   Protocol  
GigabitEthernet0/0/0              10.0.0.2/24          up         up        
GigabitEthernet0/0/1              unassigned           down       down      
NULL0                             unassigned           up         up(s)

FW的IP地址： 华为防火墙默认账号/密码：admin/Admin@123 登录后要修改密码。

<FW>dis ip in br
Interface                         IP Address/Mask      Physical   Protocol  
GigabitEthernet0/0/0              192.168.0.1/24       down       down      
GigabitEthernet1/0/0              192.168.1.254/24     up         up        
GigabitEthernet1/0/1              10.0.0.1/24          up         up        
GigabitEthernet1/0/2              172.16.0.1/24        up         up

接着 在FW中将接口划入对应的区域：

[FW]firewall zone trust 
[FW-zone-trust]add interface GigabitEthernet 1/0/0

[FW]firewall zone untrust 
[FW-zone-untrust]add interface GigabitEthernet 1/0/1

[FW]firewall zone dmz 
[FW-zone-dmz]add interface GigabitEthernet 1/0/2

配置防火墙

[FW]int g 1/0/0
[FW-GigabitEthernet1/0/0]service-manage ping permit 
[FW-GigabitEthernet1/0/0]q
[FW]security-policy 
[FW-policy-security]rule name ping
[FW-policy-security-rule-ping]source-zone local untrust trust dmz     
[FW-policy-security-rule-ping]destination-zone local untrust trust dmz 
//本意是让防护墙的区域互通，所以不做其他策略！
//工作中不建议这样配置！！！
[FW-policy-security-rule-ping]service icmp
[FW-policy-security-rule-ping]action permit 
[FW-policy-security-rule-ping]dis th
#
 rule name ping
  source-zone dmz
  source-zone local
  source-zone trust
  source-zone untrust
  destination-zone dmz
  destination-zone local
  destination-zone trust
  destination-zone untrust
  service icmp
  action permit
#
return

测试防火墙直连：

[FW]ping 192.168.1.1
  PING 192.168.1.1: 56  data bytes, press CTRL_C to break
    Reply from 192.168.1.1: bytes=56 Sequence=1 ttl=128 time=32 ms

    round-trip min/avg/max = 4/9/32 ms

[FW]ping 10.0.0.2

    5 packet(s) transmitted
    5 packet(s) received
    0.00% packet loss
    round-trip min/avg/max = 7/16/47 ms

接着配置OSPF和OSPF防火墙策略：

[R1]ospf 1 router-id  1.1.1.1
[R1-ospf-1]area 0
[R1-ospf-1-area-0.0.0.0]network 172.16.0.1 0.0.0.0

[R2]ospf 1 router-id 2.2.2.2 
[R2-ospf-1]area 0
[R2-ospf-1-area-0.0.0.0]network 10.0.0.2 0.0.0.0

[FW]ospf 1 router-id 3.3.3.3
[FW-ospf-1]area 0
[FW-ospf-1-area-0.0.0.0]network 192.168.1.254 0.0.0.0
[FW-ospf-1-area-0.0.0.0]network 10.0.0.1 0.0.0.0
[FW-ospf-1-area-0.0.0.0]network 172.16.0.254 0.0.0.0

查看邻居是否建立：

[FW-ospf-1-area-0.0.0.0]dis ospf peer brief 

     OSPF Process 1 with Router ID 3.3.3.3
          Peer Statistic Information
 ----------------------------------------------------------------------------
 Area Id          Interface                        Neighbor id      State    
 0.0.0.0          GigabitEthernet1/0/1             2.2.2.2          Full        
 0.0.0.0          GigabitEthernet1/0/2             1.1.1.1          Full        
 ----------------------------------------------------------------------------

接下来配置防火墙的OSPF策略：

[FW]security-policy 
[FW-policy-security]rule name OSPF
[FW-policy-security-rule-OSPF]service ospf 
[FW-policy-security-rule-OSPF]source-zone local dmz untrust 
[FW-policy-security-rule-OSPF]destination-zone dmz local untrust 
[FW-policy-security-rule-OSPF]action permit 
[FW-policy-security-rule-OSPF]dis th
#
 rule name OSPF
  source-zone dmz
  source-zone local
  source-zone untrust
  destination-zone dmz
  destination-zone local
  destination-zone untrust
  service ospf
  action permit
#
return

最后测试PC是否能ping通路由器：

PC>ping 10.0.0.2

Ping 10.0.0.2: 32 data bytes, Press Ctrl_C to break
From 10.0.0.2: bytes=32 seq=1 ttl=254 time=31 ms
From 10.0.0.2: bytes=32 seq=2 ttl=254 time=16 ms

--- 10.0.0.2 ping statistics ---
  2 packet(s) transmitted
  2 packet(s) received
  0.00% packet loss
  round-trip min/avg/max = 16/23/31 ms

PC>ping 172.16.0.1

Ping 172.16.0.1: 32 data bytes, Press Ctrl_C to break
From 172.16.0.1: bytes=32 seq=1 ttl=254 time=16 ms
From 172.16.0.1: bytes=32 seq=2 ttl=254 time=15 ms
From 172.16.0.1: bytes=32 seq=3 ttl=254 time=16 ms

--- 172.16.0.1 ping statistics ---
  5 packet(s) transmitted
  5 packet(s) received
  0.00% packet loss
  round-trip min/avg/max = 0/12/16 ms

试验结束，仅以此来记录本人HCIE-Datacom备考中涉及的知识点，不用作任何教学。突发奇想，想做一个自己的博客，就这样开始了，之前的试验会慢慢补齐。请理性观看，如有错误希望指正！
