At present days most of the routers allow to attach USB data storage to it providing data access to heterogeneous clients. This phenomenon is termed as NAS(Network-attached storage). So, you might achieve your goals using this router feature. First you try to pull and add files to your USB device from LAN side.

Next make sure that you are allowed to access the network from WAN side(by default firwall blocks any access through WAN side).

One more thing, you may add more than one external harddrive to the USB using USB-hub.
