Adobe Air Binary Sockets

When I Connect To My Socket开发者_运维知识库 Over My Intranet, Everything Works Fine:

var Sock:Socket=new Socket("192.168.1.100",2222);

But When I Set Up Port-Forwarding And Try To Connect Using My Real IP, I Get Error 2031:

var Sock:Socket=new Socket("76.18.24.118",2222);

What Am I Missing?
