Thanks for the feedback Seulater.
I've only really tested the FTP server via my NB internal IP address 192.168.30.2 which does work fine.
My workplace network administator has put restrictions on FTP access, so up to now I had now way of knowing
if port 21(FTP) has been working externally. DMZ has been enabled for 192.168.30.2, so I reckon that there is probably no need to do port forwarding via my modem for my Netburner.
http://www.microwebserver.net/dir actually does show where the directories/folders are stored, but this
format has some restrictions on downloading.
