Directory listing not workAre you sure this isn't a firewall issue on their end?

We already use 'fixup'.

If so, you basically have no choice but to use passive mode. If you can't, you probably will never get FTP w/ SSL to work. If you're NOT using FTP w/ SSL and it's just basic FTP, has your firewall been setup to "fixup" the FTP protocol? Since you're using NAT your firewall has to recognize the FTP traffic and re-write not just the packet headers (Source & Destination addresses) but also the internal data-frames of the FTP packets. FTP is an "old school" protocol that embeds source & destination addresses in the datagram. Probably a bad design decision back then, but in 1960-whatever no one envisioned NAT so.... it only became a problem many years later. Make sure your firewall is doing "fixup" (cisco terminology, probably called something else on other products) for FTP. Good luck. ------------------------------------------------------------------------------ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Schuessler, Doug Sent: Wednesday, February 07, 2007 10:46 AM To: [email protected] Subject: RE: [WS_FTP Forum] Directory listing not work Our firewall rules block passive mode, so that is not an option. I am unable to access the URL provided (cannot find the server or DNS error). We use 192.168.. for our internal network. Isn't this a non-routable address? ------------------------------------------------------------------------------ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Claudio Robles Sent: Wednesday, February 07, 2007 7:21 AM To: [email protected] Subject: RE: [WS_FTP Forum] Directory listing not work Doug, This is probably the most common problem in FTP, can not establish data channel. In this case, the server can not connect to the client on the ip, port specified. Most of the time this is due to firewalls blocking the new connections. I would try passive mode.
