华为AR1220L-S连网配置

以GigabitEthernet 0/0/0为wan口，GigabitEthernet 0/0/1为lan口为例

更改console口密码：
[Huawei]user-interface console 0 //进入console视图
[Huawei-ui-console0]set authentication password cipher huawei //设置密码为huawei
[Huawei-ui-console0]quit

配置接口IP地址：
[Huawei]interface GigabitEthernet 0/0/0 //进入接口模式
[Huawei-GigabitEthernet0/0/0]ip address 192.168.0.10 255.255.255.0 //配置ip地址
[Huawei]interface GigabitEthernet 0/0/1
[Huawei-GigabitEthernet0/0/1]ip address 192.168.10.1 255.255.255.0

配置ACL
[Huawei]acl 2000 //创建ACL2000
[Huawei-acl-basic-2000]rule 5 permit source 192.168.10.0 0.0.0.255 //创建ACL内容

配置接口的nat
[Huawei]#interface GigabitEthernet0/0/0 //进入WAN口模式
[Huawei-GigabitEthernet0/0/0]nat outbound 2000 //设置此接口为nat的出口

配置默认路由：
[Huawei]ip route-static 0.0.0.0 0.0.0.0 192.168.0.1 //配置默认路由

dhcp配置：
system-view
[Huawei]dhcp enable //启用dhcp
[Huawei]ip pool dhcp01 //创建dhcp01
[Huawei-ip-pool-dhcp01]gateway-list 192.168.10.1 //设置dhcp01的网关
[Huawei-ip-pool-dhcp01]network 192.168.10.0 mask 255.255.255.0 //dhcp地址池
[Huawei-ip-pool-dhcp01]excluded-ip-address 192.168.10.2 //不分配的ip地址
[Huawei-ip-pool-dhcp01]excluded-ip-address 192.168.10.3
[Huawei-ip-pool-dhcp01]dns-list 8.8.8.8 //dhcp的DNS
[Huawei-ip-pool-dhcp01]lease day 1 //dhcp释放时间
[Huawei-ip-pool-dhcp01]quit
[Huawei]interface GigabitEthernet 0/0/1 //进入接口模式
[Huawei-GigabitEthernet0/0/1]dhcp select global //启用此接口的DHCP
[Huawei-GigabitEthernet0/0/1]
