    TCP File Transfer behind NAT

    Dear All,

    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-
