To upload the torrents you need to forward a port on your router(look at your help documenstation for your torrent client). For the port forward to work after a reboot, you should also set a static IP on the machine running the torrent client.

You would also need to allow traffic on that port through your firewall.
This will keep you protected while allowing torrent traffic.

I've found the link to the speed test I posted very accurate, I would encourage trying it.
