Untangle / VSFTPD problem

Hi,

First, my apologies for "cross posting" this. As this may be a VSFTPD problem or it may be an Untangle problem, I've posted at both forums. Your patience is very much appreciated.

This week I've installed a new "Untangle" router at my office. Everything is working fine except that there is difficulty connecting to my ftp server from outside. Nothing has changed except for the router - the old one was forwarding to this FTP server perfectly.

Filezilla and IE will not connect. For some reason WinSCP is working.

From the log of Filezilla, it appears the connection is actually being made, but it "hangs" and times out when trying to receive the file listing. I've included that log below.

Please note that I've edited these logs and conf files to read our external IP address as 1.2.3.4 - I'm not actually using that IP.

If anyone can shed any light on this situation, I would very much appreciate it. We are an architectural firm and have consultants with whom we very badly need to exchange data.

Thanks in advance for any assistance.

Greg

Have you tried both active and passive connections in FileZilla?

 

Hi Falko,

Thanks for your reply. Yes, I've tried active, passive and "auto".

Any other thoughts or suggestions would be much appreciated.

Thanks again.
