Hello,

The PASV mode on a ftp transaction execute itself on the port 20, not the port 21. SO you have a problem to open the port 20 from the FTp server to Filezilla. Are you on a local lan or behind a firewall, a router, ???

Regards,

Olivier

Hi I am not 100% sure if this is a server or configuration issue on the router; can you try using some other client; or may be from the command prompt; or might be using some browser.

While googling, I found the link below:

I think the cause is your VIGOR router/NAT device not handling passive mode commands correctly.
Have you the opportunity to try with a different equipment ?

You could be right, it works ok on an old Netgear router but I need the Vigor (which is new) for remote access.

So you have three choices to resolve your problem:

1. Try to upgrade the firmware of your vigor
2. Open a ticket on th Vigor web site
3. change your Vigor with a different brand who supports your needs...
