As a typical, but perhaps high-demand home user I would like to use 2 separate ISPs. ADSL is pretty cheap nowadays, and 2 x ADSL seems a better value than one fast one — especially in terms of reliability.
If one breaks, at least the other will work.
Using an old box as a router/firewall, how can I configure a system to use two completely separate ISPs in a sensible manner?
Ideally, I'd like the load of my browsing to be balanced, but at the minimum, I'd want some kind of 'fail-over.' If I leave torrents running over night, I'd like the router to use whichever connection doesn't block the traffic — and preferably for it to reset the errant connection.
