Hello there
I plugged in my 16 GB USB to the router and config that it can be reached from the internet as FTP.
From both Windows 8 and from my Macbook, I CAN WRITE AND READ from/to this drive while im in the LOCAL network.
When I tried to reach the storage from the internet, the only option i had was READ the files that I have on the USB folder, buy try to write i got some errors.
I tried to reset to factory settings, update version again, changed accounts and passwords and nothing worked.

Any idea? i got the router one month ago

Thanks!
