我应该使用哪个IP托管聊天服务器？

Question

I made chat server in C# using

Socket s = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.TCP);
s.Bind(IPAddress.Parse(theIP),thePort);

But then I am getting a

"SocketException was unhandled, The requested address is not valid in its context"

How do I look for the correct IP to use? cmd ipconfig IPv4Address? Because that IP (I believe) is for the internal IP. I want the server IP to be an external IP address that is accessible from outside my network

Answer 1

You need to create a static path (sometimes called port forwarding) in your router binding one of your external IP/ports to an internal address and the port needed for your chat server. You will then reference your internal IP address, on your network, in your code.
