Crash connection over Internet using TCP/IP SSL sockets

Question

I'm doing a file Transfer WEB Client/server Application using TCP/IP SSL Sockets?
In an internal LAN the file Transfer work pretty well but in Internet this Crash (downturn the file transfer).
the code in Client to connect to server is:
SSLSocketFactory sslFact = (SSLSocketFactory)SSLSocketFactory.getDefault();
socket = (SSLSocket)sslFact.createSocket(c.site, c.PORT);
String [] enabledCipher = socket.getSupportedCipherSuites ();
socket.setEnabledCipherSuites (enabledCipher);
out = new ObjectOutputStream(socket.getOutputStream());
in = new ObjectInputStream(socket.getInputStream());
The code in Server to wait client connections is:
Runtime.getRuntime().addShutdownHook(new ShutdownThread(this));
try {
SSLServerSocketFactory factory = (ServerSocketFactory) SSLServerSocketFactory.getDefault();
SSLServerSocket sslIncoming =
(SSLServerSocket) factory.createServerSocket (PORT);
String [] enabledCipher = sslIncoming.getSupportedCipherSuites ();
sslIncoming.setEnabledCipherSuites (enabledCipher);
while(running) {
SSLSocket s = (SSLSocket)sslIncoming.accept();
newUser(s, pauseSyn);
} catch (IOException e) { System.out.println("Error: " + e); }
Some help with this topic, show me the ligth? what is bad?
