一、实验拓扑:
二、PC的配置#
sysname PC
dhcp enable
dns resolve
dns server 8.8.8.8
#
interface GigabitEthernet0/0/0
ip address dhcp-alloc
三、网关路由器的配置
#
sysname GW
#
dhcp enable
dns resolve
dns server 8.8.8.8
#
acl number 3000
rule 5 permit ip source 192.168.10.0 0.0.0.255
acl number 3001
rule 5 deny icmp icmp-type echo
rule 10 permit ip
#
firewall zone trust
priority 10
#
firewall zone untrust
priority 5
#
firewall zone Local
priority 15
#
firewall interzone trust untrust
firewall enable
packet-filter 3001 inbound
detect aspf ftp
detect aspf sip
detect aspf rtsp
detect aspf http
detect aspf http java-blocking
detect aspf http activex-blocking
#
interface GigabitEthernet0/0/0
ip address 192.168.10.1 255.255.255.0
zone trust
dhcp select interface
dhcp server dns-list 8.8.8.8
#
interface GigabitEthernet0/0/1
ip address 211.1.1.2 255.255.255.0
nat outbound 3000
zone untrust
#
ip route-static 0.0.0.0 0.0.0.0 GigabitEthernet0/0/1 211.1.1.1
#
user-interface vty 0 4
authentication-mode password
set authentication password cipher huawei
user privilege level 3
四、公网路由器的配置
#
sysname INTERNET
#
ip host www.baidu.com 100.100.100.100
ip host www.google.com 200.200.200.200
#
dns resolve
dns server 8.8.8.8
dns proxy enable
#
interface GigabitEthernet0/0/0
ip address 211.1.1.1 255.255.255.0
#
interface NULL0
#
interface LoopBack0
ip address 100.100.100.100 255.255.255.0
#
interface LoopBack1
ip address 200.200.200.200 255.255.255.0
#
interface LoopBack100
ip address 8.8.8.8 255.255.255.0
#
user-interface vty 0 4
authentication-mode password
set authentication password cipher huawei
user privilege level 3
#
