FTP error 425

Hello everyone,

I'm setting up my FTP server, I'm behind a Freebox that I'm using in router mode.

On my router, I've configured my port forwarding like this:
TCP protocol forwarding on port 21 to the machine where the server is running on port 21
TCP protocol forwarding on port 20 to the machine where the server is running on port 20

I asked a friend to test it, and he receives an error like "Error: Failed to read directory content"
on my server, I have an error "425 Can't open data connection."

This error appears when the client sends the LIST command.

Does anyone know how to fix this?

Thanks in advance

Configuration: Windows XP Firefox 2.0.0.6

I had this problem, and after reconfiguring everything in IIS, I noticed that there is a page 3 of the Windows XP Pro firewall - Advanced tab -> "network connection settings" (top frame). It turns out that I had added an Ethernet card to my machine, as the built-in RJ45 port of the motherboard was worn out. But I had forgotten to check the FTPServer service on that connection, which is linked to my router (Freebox) where I had opened port 21, which allowed the connection but not the data transfer.

It is possible that this is not the only solution for error 425.

I found this one after completely disabling the firewall: error 425 disappeared, and FTP worked perfectly from the outside.

If it doesn't work by checking FTP Server on the connection linked to the Internet, nor by completely disabling the firewall, then it's something else...
