Active FTP behind router on a Cable Modem Connection
Posted on 2005-05-11
I have a custom Visual Basic app that runs some automated procedures over FTP. I have recently moved office locations and now the application no longer works.
CuteFTP works in Passive mode. But IE and the command prompt both do not work in active mode. I understand how the modes work and I know that Active mode requires the server to open connections to the client and that a client firewall could interfere with this.
I suspect that because active FTP is not working, the custom app runs over active FTP. Can anyone tell me how I can get around this? Would an FTP proxy work? How do I set this up? Or would it be possible to configure my router to accept these connections? Recoding the app is the last thing that I want to do, so please assume that it has to run active FTP. Im just looking for a way to make this work.
