从Internet连接到服务器插槽到通过LAN连接到Internet的系统

Question

I want to connect to a server which is connected to internet via LAN. So in the client side i need to write code like new Socket("i dont know the ip",PORT_NO) Here which ip address should i give? Its obvious that i can't give both LAN ip address as well as local address of the server.

Answer 1

You server should be running on a machine with public IP. You cannot give private IP ie address server got using DHCP when it is connected to LAN. You may need to do more configuration on your router to get the packet to your listening java server.

Answer 2

您将需要提供您的LAN ip地址，因为每个设备的localhost ip都是相同的。
