Load Balancing with iptables

Hello,

I'm looking for help on my configuration.

I have actually the following network :

Internet

-------ppp0---------ppp1-------

| Linux Router |

| FTP/WEB server |

| |

-----------------eth0--------------

LAN

(10 computers)

Because of my little bandiwth on the two ppp links (1024/256),

I'm looking for doing load balancing in two ways :

I want to have the computer on the LAN being masqueraded dynamically with one of the ppp link (the least loaded).

And, if it's possible, have connections to my web/ftp servers being balanced through the two links (like BGP do, but as far as i know,

i can't have BGP on xDSL links).

For the internal routing, I'm thinking about masquerading on a teql virtual interface, but dunno if it could work.

And for external balancing, i've heard about DNS balancing, but haven't found any paper on it.

Is there any iptables script or patch for these purposes ?

Thanks for help,
