Please log in for more thread options Can anyone tell me, how to write such a program that can transfer files (either binary or text) behind NAT devices( such as for computers behind firewalls and routers and other NAT devices) using TCP socket programming. I have a mechanism through which the public IP of the router and Port number will be forwarded to me. But after that I am not sure that simple TCP/IP socket programming will suffice or I need to do something more for that. If you have any article link or article or any example that shows how the File Transfer can be done for such a case then please help me regarding this. Any sought of help or idea will be appreciated from you all. from- Saurabh Srivastava | ||||||||||||||||

Please log in for more thread options Have a look at `ftp` or `scp` source code (either Linux or BSD). NAT should be transparent, but you must either originate inside the NAT zone, or specifically configure the NAT device to route incoming requests to a particular server. -- Robert | ||||||||||||||||
