I am looking for a solution to take 4 or more ADSL lines with PPPoE and a Static IP and then have my Local network behind them. I was reviewing http://lartc.org/howto/lartc.rpdb.multiple-links.html and it looks like a good solution. How can the document be modified to do NAT from the local network? I would need the local network to be NATed to the WAN. How can I set it up so that the external interfaces login via PPPoE?
