今天突发奇想，想让自己的树莓派某个端口自动映射到公网，想起来路由器有个UPNP功能并且已经开启，那树莓派肯定也可以利用这个功能自动把对应端口映射到公网之上，想到这里于是乎我上网搜到一个linux下的小工具名为：MiniUPnP

于是下载下来传到树莓派上编译安装
这里也提供给大家下载链接

本站下载：

miniupnpc-2.0.20180222.tar

 

下面举个例子：

增加一个UPNP设置，把本机的80端口映射到网关的8008端口：

upnpc -a 192.168.88.162 80 8008 TCP

删除这个设置:

upnpc -d 8008 TCP

下面是运行后的结果：


root@raspberrypi:~# upnpc -a 192.168.88.162 80 8008 TCP

利用这个命令大家完全可以自己编写一个启动脚本，当树莓派启动之后自动运行来提交端口映射。
