Socket server and white ip?

Question

Java

Yesterday I bought a white address from the provider, and decided to connect to the server, as a result, nothing happens.
It seems that I am doing everything right:
(I start the server and listen on the port)
In the client, I specify the address (which was given to me by the provider, that is, white) and the port that is on the server.

Socket fromServer = new Socket(ip, port);
  ObjectOutputStream out = new ObjectOutputStream(fromServer.getOutputStream());
  ObjectInputStream in = new ObjectInputStream(fromServer.getInputStream());

What am I doing wrong? (Everything works on the local network)

Answer 1

Do you happen to have everything going through the router?
Or is the network cable from the provider directly plugged into the server?
Or port forwarding configured?
