为何阿里
服务器
下的
内网ip端口
，能够与公网ip
端口
一一对应？
这种一一对应是如何做到的，表面上看公网ip所有
端口
都在为这个单一
内网ip
服务。那如何做到公网ip向内网下的所有
服务器
服务啦？比如两台
服务器
都开放3000
端口
，那么公网：3000该提供谁的服务啦？下图是我使用的截图：阿里

是

如何让用户通过

访问阿里云的
内网端口
上的服务？
现在我们的服务启动好以后是在内网的ip
端口
上（
内网ip
:5050）。试问可不可以通过
服务器
的外
网ip
来访问到这个服务（比如:外网固定ip:5050）？或者是有没有第三方的软件可以实现这个功能？我们的系统是ubuntu server14.04
