华为NAT基本配置_华为nat配置

client1：192.168.1.1 gw：192.168.1.254

client2:192.168.1.2  gw：192.168.1.254 

私有地址：

（1）a: 10.0.0.0 ~ 10.255.255.255/8

（2）b: 172.16.0.0 ~ 172.32.255.255/12

（3）c: 192.168.0.0 ~ 192.168.255.255/16

NAT的类型：

（1）静态NAT：一对一，内部本地地址—>内部全局地址

（2）动态NAT：在地址池选一个空闲的地址进行转换，先到先得

（3）端口复用NAPT：192.168.1.1-->100.1.1.0:2048

                                     192.168.1.2-->100.0.0.0:2059

                                      192.168.1.3-->100.0.0.0:2050

（4）easy ip：类似于NAPT，但没有地址池，都可以通过
