TCP/IP connection in UDF Timeout

Question

Hi Guys,
Can someone please tell me if there's some way to trace this. I'm doing a TCP/IP connection to an external server from our PI Dev system in a UDF. I've designed this code in an external java tool and everything works fine. I can send the message over the protocol and I get a response back but if I test the UDF in my MM it times out and kicks me off the network. I've asked the firewall guys to have a look but all they they there's no scanning on this rule and nothing's being blocked. I need to find out how come I can't get a connection to this IP and Port. Any idea? Also would I be able to run a tracert command in R/3 itself?
Thanks,
Jan

Hi,
I've tested my code in my 3G which gets a connection and send/receive data. However if I deploy it on PI It times out after a while. At  s.connect(serverAddress, 30000); it can't get a connection to the host. There's no error message, just times out. I'll see what I can come up with working with the network people. They just HAVE to do a trace on it.
try
            System.out.println("Creating Socket: " + ip + ":" + port);
            //Create Socket Address
            SocketAddress serverAddress = new InetSocketAddress(ip, Integer.parseInt(port));
            s = new Socket();
            //Set Keep Alive Parameter
               s.setKeepAlive(true);
               //Set Read/Write Timout
               s.setSoTimeout(20000);
               //Open Connection with Address + Process Timout
            s.connect(serverAddress, 30000);
            System.out.println("Socket Created: " + s);
        catch(UnknownHostException uhe)
            // Host unreachable
            System.out.println("Unknown Host :" + ip);
               errorTrace+=(";Unknown Host :" + ip);
            s = null;
