How do i turn my book live into a FTP server?

I have tried some of the things i found but when i put in address it just goes to the UI login. Opened port:21 on router, i don’t however have a static ip but im using no-ip.com forwarding it to my ip address. Any idea’s?

No-ip will point to IP address that represents your home.  Me think you have a router and then PC and mybooklive box connected to it.  The Router need to forward the FTP port to your mybooklive.  that will require you to set up static IP to your box otherwise your router doesnt know which node it should route the FTP request.
