是什么导致客户端无法连接到服务器？
[英]What could be preventing a client from connecting to the server?
问题描述
My client connects to my Server very well locally (in a LAN through a router) but when I try to connect my client to a server on a IP that is not in my LAN, it doesn't work. 
我的客户端很好地在本地连接到我的服务器（通过路由器在LAN中），但是当我尝试将客户端连接到不在LAN中的IP上的服务器时，它不起作用。 What could be the problem? 可能是什么问题呢？

The server is behind a NAT or a firewall or both. 服务器位于NAT或防火墙或两者之后。 You need to allow inbound connections on the port in any firewalls on the server's network (including a software firewall that might be running on the server), and if it is behind a router/NAT you will need to set up that router to forward the desired port to the servers internal IP address. 您需要在服务器网络上任何防火墙（包括可能在服务器上运行的软件防火墙）的端口上允许入站连接，并且，如果该防火墙位于路由器/ NAT之后，则需要设置该路由器以转发该路由器。服务器内部IP地址的所需端口。 Also remember that your server's local IP 192.168.xx is probably different than the IP you'll need to connect to (the IP that your router gets from the ISP). 还要记住，服务器的本地IP 192.168.xx可能与您需要连接的IP（路由器从ISP获取的IP）不同。
