I think all you need to do is try it. One way is .... in your home network setup a harddrive (e.g. one attached to your modem/router via its USB port), understand what address scheme to use in order to read/write files, et.c from a PC or your phone, once this works for you, enter this address into the config dialog described before and test it.
Are you looking for something else ? or sth more then this ? what could that be ?
