I am looking at an external enclosure for an IDE HDD. The enclosure has a RJ45 port on it to link with network. What I was wondering, and this may be way out there, can the router be set to where this drive be accessed from outside the LAN via an ftp port. I want to be able to download to, and upload from this drive without opening any ports on my computers. I don't know if I have explained myself well enough here but please help me if you can. Here is a pic of the external case I was looking at.
