拓扑图
为pc路由器配置Easy IP的上网方式
1、ar路由的配置：
<Huawei>system-view #进入系统视图
[Huawei]sysname ar #修改路由器名称为ar
[ar]interface GigabitEthernet 0/0/0 #进入接口0/0/0
[ar-GigabitEthernet0/0/0]ip address 10.11.12.100 24 #配置ip地址及子网掩码
[ar-GigabitEthernet0/0/0]ping 10.11.12.1 #检测是否可以访问网关
PING 10.11.12.1: 56 data bytes, press CTRL_C to break
Reply from 10.11.12.1: bytes=56 Sequence=1 ttl=128 time=80 ms
Reply from 10.11.12.1: bytes=56 Sequence=2 ttl=128 time=10 ms
Reply from 10.11.12.1: bytes=56 Sequence=3 ttl=128 time=10 ms
Reply from 10.11.12.1: bytes=56 Sequence=4 ttl=128 time=10 ms
Reply from 10.11.12.1: bytes=56 Sequence=5 ttl=128 time=20 ms
--- 10.11.12.1 ping statistics ---

round-trip min/avg/max = 10/26/80 ms
[ar-GigabitEthernet0/0/0]quit #退出接口
[ar]dhcp enable #开启dhcp功能
Info: The operation may take a few seconds. Please wait for a moment.done.
[ar]interface GigabitEthernet 0/0/1 #进入接口0/0/1
[ar-GigabitEthernet0/0/1]ip address 192.168.1.1 24 #配置IP地址及子网掩码
[ar-GigabitEthernet0/0/1]dhcp select interface #dhcp选择基于接口
[ar-GigabitEthernet0/0/1]dhcp server dns-list 114.114.114.114 #配置dns
[ar-GigabitEthernet0/0/1]quit #退出接口
[ar]acl 2000 #创建基本acl 2000
[ar-acl-basic-2000]rule permit source 192.168.1.0 0.0.0.255 #规则允许源地址及长度
[ar-acl-basic-2000]quit #退出acl 2000
[ar]ip route-static 0.0.0.0 0.0.0.0 10.11.12.1 #创建默认路由并指向外网网关
[ar]interface GigabitEthernet 0/0/0 #进入接口0/0/0
[ar-GigabitEthernet0/0/0]nat outbound 2000 #配置nat的方向为out
[ar-GigabitEthernet0/0/0]quit #退出接口
2、检测可以访问外网
查看ip地址获取情况及ping网关
PC的IP地址及ping网关
ping百度
ping百度
3、路由器上查看nat out：
[ar]display nat outbound #查看nad out
NAT Outbound Information:
