Hiding FTP details from programmers. FTP redirection?

Hi,

I want a solution where I can hide FTP details from programmers but still allow them to connect to it. So that they cannot connect to server outside of office.

Is there any way to do ftp redirection or forwarding or tunneling or whatever it can be called.

What I am thinking is to find a way where programmers connect to ftp which is address of our local computer (or fake address). Now when they connect to this ftp they are actually connected to real remote ftp server. They do not have to provide a password that will be filled automatically by the program which is doing redirection.

Is there any way to do it?

Thanks in advance
