WS_FTP - Error: 500 Illegal PORT command

Question/Problem: When I try to connect I receive the following error.

500 Illegal PORT Command
! port cmd failed.
! DoDirList failed 0

The 500 illegal PORT command error can be helped by enabling the 'Passive Transfers' in Options > Session tab > "Use Passive Transfer Mode".

Another method is in Session Properties > Advanced tab > Passive transfers. Don't forget to save by clicking the Apply button!

In version 7.5+ the passive mode option can be found by clicking once on your site profile within the "connect to remote host" window, then click "edit" to the right.
