华为ar路由器设置一对一NAT(华为ar系列路由器设置)

静态NAT

有些环境需要单独指定公网IP地址上网，可以使用静态NAT的方式来实现

1、AR路由器的配置

system-view #进入系统视图 Enter system view, return user view with Ctrl+Z. [Huawei]sysname ar #修改名称 [ar]interface GigabitEthernet 0/0/1 #进入接口0/0/1 [ar-GigabitEthernet0/0/1]ip address 10.11.12.100 24 #配置IP地址及子网掩码 [ar-GigabitEthernet0/0/1]ping 10.11.12.1 #检测连通性 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=70 ms Reply from 10.11.12.1: bytes=56 Sequence=2 ttl=128 time=20 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=20 ms Reply from 10.11.12.1: bytes=56 Sequence=5 ttl=128 time=10 ms --- 10.11.12.1 ping statistics --- 5 packet(s) transmitted 5 packet(s) received 0.00% packet loss round-trip min/avg/max = 10/26/70 ms [ar-GigabitEthernet0/0/1]quit #退出 [ar]ip route-static 0.0.0.0 0.0.0.0 10.11.12.1 #配置默认路由，指向外网网关

2、配置PC的IP地址及网关等

配置pc的IP地址和网关等信息

3、配置内网的网关等信息

[ar]interface GigabitEthernet 0/0/0 #进入接口0/0/0 [ar-GigabitEthernet0/0/0]ip add 192.168.1.1 24 #配置IP地址及子网掩码 [ar-GigabitEthernet0/0/0]ping 192.168.1.254 #检测连通性 PING 192.168.1.254: 56 data bytes, press CTRL_C to break Reply from 192.168.1.254: bytes=56 Sequence=1 ttl=128 time=40 ms Reply from 192.168.1.254: bytes=56 Sequence=2 ttl=128 time=10 ms Reply from 192.168.1.254: bytes=56 Sequence=3 ttl=128 time=10 ms Reply from 192.168.1.254: bytes=56 Sequence=4 ttl=128 time=20 ms Reply from 192.168.1.254: bytes=56 Sequence=5 ttl=128 time=20 ms --- 192.168.1.254 ping statistics --- 5 packet(s) transmitted 5 packet(s) received 0.00% packet loss round-trip min/avg/max = 10/20/40 ms [ar-GigabitEthernet0/0/0]quit #退出接口

4、配置nat一对一映射

[ar]interface GigabitEthernet 0/0/1 #进入接口0/0/0 [ar-GigabitEthernet0/0/1]nat static global 10.11.12.101 inside 192.168.1.254 #配置外网地址及内网地址的静态映射 [ar-GigabitEthernet0/0/1]quit #退出接口

5、查看静态NAT映射信息

[ar]display nat static #查看静态nat信息 Static Nat Information: Interface : GigabitEthernet0/0/1 Global IP/Port : 10.11.12.101/---- Inside IP/Port : 192.168.1.254/---- Protocol : ---- VPN instance-name : ---- Acl number : ---- Netmask : 255.255.255.255 Description : ---- Total : 1
