First convert your USB connection to UTP cat 5 via a belikin hub then buy yourself a Sonic firewall and enable DHCP in it, Configure the firewall to deliver Dns gateway etc and then your away. I have this type of system at home and it works like a dream i have never been hacked "got a few people kicked of there ISP for trying" And as the ADSl connection is always on you are fully protected as long as you config Sonic correctly. ht*p://sonicwall.com How do i know all this !! I am a system engineer working for a major communictations company contracting to BT ignite.. Hope this helps..
