The client and server written in qt

Listen I write of a service is a server - & gt; Listen (QHostAddress: : Any, 8888);
The client socket connection - & gt; ConnectToHost (QHostAddress (IP), 8888);

I'm on my own computer to open the server and the client, the client can connect to the server, but when I go up someone else's computer with clients to connect my server (in my computer has been open), even, I also changed the IP (I IP directly out of the IP) on baidu, I take the past, the service side directly connect the computer is not opened, and the port of the client or not, only the client and the server are on my computer to connect, how to solve this problem, just learning qt soon, for the first time contact network communication, search on the Internet a lot, didn't find how to solve,
