1. For FTP data connection type, what is the difference between PASSIVE and PORT mode?
2. Would the routers configuration(along the path from FTP server to client) affect the data transfer while using different FTP data connection type? Background for the above questions: When I connect my PC to cable modem directly, I have no problem with browsing a FTP site(FTP client is set to PASSIVE mode). After I add a router(sorry, it's not cisco) between the PC and cable modem, connecting to the same FTP server will have an error like "Unable to set up passive listening socket". The problem can be solved by change the FTP client data connection type to PORT mode. Thank you for your feedback in advanced! B.L. __________________________________________________ Do You Yahoo!?
