title: Java TCP/IP Server - Client Communication over the internet
body: <p>I'd like to get a tcp/ip connection working over the internet. I already have two classes, one tcpserver which handles requests and a tcpclient which connects, sends and receives data.</p>
  
  <p>Until now I had it working perfectly on local networks. The usual 127.0.0.1 / localhost and my 192.168.xxx.xxx adresses are not giving any problems.</p>
  
  <p>My question is, what do I have to do to make it work over the internet. As I might want to do some research involving a simple http/server I need this to work.</p>
  
  <p>I doubt its my firewall but maybe its the ISP that blocks this type of connection. Anybody has an idea?</p>
