winSCP not listing directory problem

Question

I'm trying to use winSCP to FTP my server using FTPs and then synch with a backup folder. I have had this working fine from a PC on my work intranet (i.e. the same domain) however when I try to set it up off site (which is my whole point) the same script fails. The FTP log is as follows..

This fails whether I run from GUI or a previously tested and working scripted version. It looks from the log like theres a problem with a timeout on the directory listing, presumably it works locally as less lag

Any ideas if this is a winSCP setting (and if so where) or on the FTPserver side (Windows Web Server 2008 R2) ?

Sorry about the imnage file, the log unformats to a wall of text, even if wrapped in a pre tag :-( — Saul, Sep 09 '10 at 15:11

I ran into this problem when I forgot to open the extra ports that Passive FTP mode requires.

Basically, you need to open/allow a range of ports through your firewall in addition port 21 that you have already opened.

It looks like you are using Microsoft's FTP Server. Microsoft has a support page with instructions here.

When I did this, I opened port 21 for the control port, and then arbitrarily chose ports 65000-65050 for the Passive FTP Data. Your range will vary based on the number of concurrent users/sessions you need or expect (more concurrent users/sessions require more open ports) and any other ports that are already open for other applications.

Stumbled upon this myself. Many pages have the same question, but often not the (full) answer. It's the PASV ports that need to be reachable in PASV mode. This may need the firewall/IPtables to be adjusted:
