FTP cannot connect to any of my 20+ sites

[Zvi Lando]

As you can see from my level 3 debugging, I cannot connect to any of my sites. I am using version 3.8.0 and even tried reinstalling...

Here is the log:

This is not a problem with FileZilla Client as-is, but with your setup.

At this moment you are connected to the FTP server. Works.

Command: TYPE I
Response: 200 Type set to I.
Command: PORT 10,0,0,1,194,182
Response: 200 PORT command successful.
Command: LIST

Error: Connection timed out

You tell the FTP server to connect to IP address 10.0.0.1. But this is a local IP address in your local network, and not in the FTP server's network.

Use passive mode, send a proper IP address or fix your transparent FTP proxy. Not a bug.
