3 ISP Load Balancing?
 

Hi;
My English is not very good. You try to explain my problem :)

I am trying to Load Balancing with Debian, a result of researches
I found many documents, but will have some questions for you.

1 ) 3 units have ADSL line. I would like to combine these lines. Torrent files or as heavy as it
I can speed equivalent to the time I've downloaded all three, but the speed tests
The only two I can speed. Why is this? In addition, programs like Internet banking or msn messenger, internet drops every 10 minutes. How can I fix this?

2 ) ADSL Line of 3 combine their access to the outside, inside I want to redirect my servers on my network I use a variety. How can I get it? I guess what NAT with iptables, but if I was not going to do with.

3 ) I have my line, one 3G, I would like to combine it was triggered automatically when the first ADSL line drops. Bonding and so on. I looked at many things but can not get into the job, it would show the document to me?

I apply the parts of the documentation I have written here I apply for Load Balancing. http://pastebin.com/LKwkN7Nd

Thank You...
