question about HTTPS option in BlackPole image

Hi, i am trying to get FTP connection over the internet (not local connection) with the app iDreamX for mac (superp app by the way), and the ports i forwarded in my router is HTTPS:443, FTP:21 and Telnet:23. So the challenge is that in BlackPole wich i use on my VU+Duo there seems to be no option with HTTPS..only normal HTTP. But in BlackHole that i use on my VU+Uno there is a option with HTTPS?? Can anyone tell me if it is possible to setup HTTPS in BlackPole image or maybe download another webif plugin? Can anyone help please! -Thanks in advance!!
