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...
Hence the need for two power systems, preferably from two different utilities.

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.
And if the continent sinks, you're still fucked.
Get 2 houses with 2 power lines and 2 ADSL providers each on 3 different continents.
Of course, if aliens destroy the planet...
And don't forget the solar system...
And wasn't Milky Way about to collide with an another galaxy anyway?
If he has got backhoe what the hell would he be doing fooling around on the internet? He'd be cooling out on the backhoe!
and even if you have ups's for both, your house could be destroyed, better have a back up house
Or, you know, a laptop.
It is dangerous to be right when the government is wrong.
Thats easy .. get your own autonomous system number, network block and have both ISPs toss a BGP session your way.
It'll be easier than figuring out the iptables commands necessary to implement what you want...
Besides you would be doing the Internet a service...more route flap and increased CIDR fragmentation is just a preview of what IPv6 will digress into after having been deployed for a few years.
Your life probably will not end if you're not online 24x7x365.
But why risk it?
Mate, there is a reason why some of us (read: Most non-USA'ians) refer to the US as a developing country ...
