华为防火墙安全策略配置
一、配置要求及拓扑;


要求:
1、Trust区域用户可以访问Untust区域与DMZ区域用户;
2、Untrust区域用户只能访问DMZ区域ICMP与Telnet流量;
3、DMZ区域用户即不能访问Untrust区域和Tust区域;
4、区域trust内只允许源地址为192.168.1.0/24,ICMP ;
二、基础配置
防火墙huaweiFW

system-view 
sysname huaweiFW
interface GigabitEthernet0/0/0
 ip address 202.100.1.10 255.255.255.0
quit
interface GigabitEthernet0/0/1
 ip address 172.16.1.10 255.255.255.0
quit
interface GigabitEthernet0/0/2
 
 ip address 192.168.1.10 255.255.255.0
quit
interface GigabitEthernet0/0/3
 ip address 192.168.10.10 255.255.255.0
quit
firewall zone trust
 add interface GigabitEthernet0/0/2
 add interface GigabitEthernet0/0/3
 quit
firewall zone untrust
 add interface GigabitEthernet0/0/0
 quit
firewall zone dmz
 add interface GigabitEthernet0/0/1
 quit
 
AR1:
system-view 
sysname AR5
interface GigabitEthernet0/0/0
 ip address 192.168.10.1 255.255.255.0 
quit
ip route-static 0.0.0.0 0.0.0.0 192.168.10.1

AR2

system-view 
sysname DMZ
interface GigabitEthernet 0/0/0
ip address 172.16.1.1 24
quit
ip route-static 0.0.0.0 0 172.16.1.10

AR3
system-view 
sysname trust
interface GigabitEthernet 0/0/0
ip address 192.168.1.1 24
interface loopback0
ip address 2.2.2.2 32
quit
ip route-static 0.0.0.0 0 192.168.1.10
quit
AR5
system-view 
sysname trust
interface GigabitEthernet 0/0/0
ip address 192.168.1.1 24
interface loopback0
ip address 2.2.2.2 32
quit
ip route-static 0.0.0.0 0 192.168.1.10
quit
三、防火墙策略配置
防火墙默认策略为:
#                                         
 firewall packet-filter default permit interzone local trust direction inbound
 firewall packet-filter default permit interzone local trust direction outbound
 firewall packet-filter default permit interzone local untrust direction outbound
 firewall packet-filter default permit interzone local dmz direction outbound
firewall session link-state check ==启用会话链路状态检查
firewall packet-filter default deny all ==拒绝所有流量
配值安全访问策略
Trust区域用户可以访问Untust区域与DMZ区域用户
firewall packet-filter default permit interzone trust untrust direction outbound
firewall packet-filter default permit interzone trust dmz direction outbound

Untrust区域用户只能访问DMZ区域ICMP与Telnet流量
policy interzone dmz untrust inbound
 policy 1
  action permit
  policy service service-set icmp
  policy destination 172.16.1.1 0
 policy 2
  action permit
  policy service service-set telnet
  policy destination 172.16.1.1 0         
  查看会话:
[huaweiFW]display policy interzone untrust dmz inbound
15:17:51  2015/02/02
policy interzone dmz untrust inbound
 firewall default packet-filter is deny
 policy 1 (2 times matched)
  action permit 
  policy service service-set icmp (predefined)
  policy source any
  policy destination 172.16.1.1 0

 policy 2 (4 times matched)
  action permit 
  policy service service-set telnet (predefined)
  policy source any
  policy destination 172.16.1.1 0

[huaweiFW]   
DMZ区域用户即不能访问Untrust区域和Tust区域(可以不用配置因为前面以拒绝过一次流量了)

区域trust内只允许源地址为192.168.1.0/24,ICMP ;
policy zone trust
 policy 1
  action permit
  policy service service-set icmp
  policy source 192.168.1.0 mask 255.255.255.0

 policy 2
  action deny
