Working With 2 ISPs For Home Networking?

An anonymous reader writes "This is, I think, a simple question — but one which I can't get the answer to. 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. Ideas?"

and even if you have ups's for both, your house could be destroyed, better have a back up house,

but make sure its not in the same neihborhood as your primary...

It's easy

You just get a Linux box with 2 NICs and start adding static routes :

route add 1.1.1.1 255.255.255.255 eth0
route add 1.1.1.2 255.255.255.255 eth1
route add 1.1.1.3 255.255.255.255 eth0

Etc, etc....

It might seem like a big job, but there's huge ranges of reserved addresses you can skip. Let us know how you get on.
