一，用固定的公网ip做映射命令
System
int dialer 0
[Quidway-Ethernet3/0] nat server Protocol tcp global 200.200.200.1 外网端口 inside 192.168.1.254 内网端口
[Quidway-Ethernet3/0] nat server protocol tcp global 200.200.200.1 外网端口 inside 192.168.1.254 内网端口
【提示】
1、global后跟公网地址，inside后跟的是私网服务器地址，www和ftp可以改为端口号
2、内部用户不能使用公网地址来访问内部服务器,必须使用内网地址访问.，如
192.168.1.0/24网段的用户,不能访问,而只能访问
二，如果没有固定ip,对于上面命令要作修改，修改如下
system
int dialer 0
nat server pro tcp global current 内网端口 inside 192.168.1.2 外网端口
删除命令
在前面加上undo nat server pro tcp global current 内网端口 inside 192.168.1.2 外网端口
三，display nat all命令用来显示所有的地址转换的配置信息

1：监控级
【参数】
无
【描述】
display nat all命令用来显示所有的地址转换的配置信息。
