apparently people have been having a ton of trouble getting FileZilla to make a connection by issuing the PORT command, so here’s the scoop on how to do it (per saved connection under “Site Manager”, FileZilla v.3.3.1).
* Open Site Manager
* Select the site in question that needs to connect with PORT command
* Choose the “Transfer Settings” Tab
* Under “Transfer Mode”, select the “Active” radio button option
* Save settings by Clicking the OK Button.
Congrats! – You connection will issue PORT command whence connecting.
