I want to download torrent files to a fashdrive attached to modem or router (local server ) by initiating the download from the mobile device

I want to download torrent files from my mobile but since I don't have enough storage I want the files to be downloaded to my local server (the flashdrive/pendrive attached to my modem which can be accessed wirelessly), Is there a way to do this? I don't want my laptop running continuously for downloading torrent files, instead I would like to use my mobile phone but the problem is that I have very limited storage in my android device. Is there a way to download to a remote Pendrive or storage device attached to my modem or router? Thanks in advance.
