425: Unable to open the data connection

#1 Post by Keith » 2006-08-20 14:37

I have set up an FTP site that is easily accessed by most computers with a few exceptions - the responses below show the problem that my home PC has. I have no problem connecting to other FTP sites using my home PC. Could you please suggest how I can go about resolving this?

The FTP server I am having a problem connecting to is a Cerberus System. The incoming FTP call is redirected from our static IP address to my work PC.

Keith :(

Set your firewall to allow FileZilla to establish outgoing connections to all ports.

Can you identify what it is that is not correctly set up on the server?

It's very much the Passive mode settings. The IP address returned is a LAN address (It should be the external address of the server).
