华为路由器配置网络地址转换NAT实现访问互联网

配置思路

配置动态地址转换的思路如下：

配置接口IP地址、缺省路由和在WAN侧接口下配置NAT Outbound，实现内部主机访问外网服务功能。

操作步骤

1、在Router上配置接口IP地址

<Huawei> system-view
[Huawei] interface GigabitEthernet 0/0/0
[Huawei-GigabitEthernet0/0/0] ip address 30.30.30.100 255.255.255.0 
[Huawei-GigabitEthernet0/0/0] quit
[Huawei] interface GigabitEthernet0/0/1
[Huawei-GigabitEthernet0/0/1] ip address 192.168.10.1 255.255.255.0 

2、在Router上配置缺省路由，指定下一跳地址为30.30.30.1。

[Huawei] ip route-static 0.0.0.0 0.0.0.0 30.30.30.1

3、配置ACL

[Huawei]acl 2000
[Huawei-acl-basic-2000]rule permit source 192.168.10.0 0.0.0.255

4、在外网接口中配置NAT Outbound

[Huawei] interface GigabitEthernet 0/0/0
[Huawei-GigabitEthernet0/0/0] nat outbound 2000

5、验证配置

[Huawei]display nat outbound
 NAT Outbound Information:
