If you have 2 adsl lines you can get a router that will bundle the bandwidth together.

I think Draytek do something like that.

I'm guessing though that you wanted to do it so it doesnt cost you anything.

Well that lartc chapter gives you the right information. we aren't just going to recite it all. Where did you come unstuck? What worked, what didn't? you need to learn to help yourself if you want us to help you aswell.
