Hallo ich habe das Problem das sich zwei Computer bei mir zuhause sich über interne IP's mit Sockets nicht verbinden ich habe Folgenden Quelltext:
Client.java:
MainFrame.java:
Server.java:
ChatDienst.java:
Bitte einfach eine Lösung in Codeform schreiben danke.:toll:

String hostName = (IP);
int port = (Port);
Socket c = null;
try {

port = 25565;
c = new Socket (hostName,port);
BufferedReader vomServer = new BufferedReader(new InputStreamReader(c.getInputStream()));
PrintWriter zumServer = new PrintWriter(c.getOutputStream(),true);
BufferedReader vonTastatur = new BufferedReader(new InputStreamReader(System.in));
text = (vomServer.readLine());
MainFrame.newText(text);
c.close();
}catch (Exception e) {
e.printStackTrace();
