[SOLVED] FTP Server problems

By link470 ·
Hi everyone.

For as long as I can remember I've had problems with FTP access on my own servers. I started out running IIS as an FTP server, hosting the server behind a Linksys NAT Router [BEFW11S4, quite old], and opening port 21 to that server. I could never make it work, no matter how many times I tried. If you opened Internet Explorer or firefox and navigated to the ftp server, you got a login screen, and could enter your information, but then nothing happened. It wouldn't connect properly.

Anyways, I left IIS, and have been using WS_FTP Server instead. It's seemed to do a good job. I use that behind my new Dlink DIR-655 router with port 21 forwarded to the server, but still, doesn't work as smoothly as I'd like it to all the time. I can access the server perfectly through the command line, although I have problems sending and receiving files, and through IE, I still can't connect to the FTP server. It gives me errors. My Mac running Cyberduck won't connect to it either. It works fine if I use an internal address and am accessing it within the network, but still not in Internet Explorer. Anyways, I'm just wondering if it's really that hard to run an FTP server from home. I'm an MCSE level and still can't do it and I'm not sure if I'm just missing the most simple concept or if I should be doing something differently. Home cable modem>Dlink Router>port 21 forwarded to server. Works for some people through a client, but not everyone and not all the time. It changes regularely. If anyone has any experience with any of these problems please let me know. It would be greatly appreciated. Thanks!

Hi There,
To have consistent results you need to configure a port forwarding range for PASV FTP. These are the ports that the server will be telling the client to use when making a connection back to the server and for the actual data transfers. (Usually a range of 5 ports is more than enough) IE and Firefox will both use PASV by default. I don't know exactly where the PASV settings are is WS.
