But for help, I have found the nano-howto extremely useful. http://www.ssi.bg/~ja/nano.txt


I think this will work... I've made some preliminary tests, a simple
multipath default route:
 ip route add default proto static  nexthop dev ppp0 nexthop dev ppp1
and I saw packets going out from both of the interfaces.

I've also tried to setup MLPPP on the PPPOE links but it seems that the
DSLAM on the other side didn't support this.

If you want true bonding, you need someone on the other side of the links to "unbundle" for you. That means either your ISP(s) or you can also have a system on the internet and create a tunnel to that host over the links. It was described today under the subject "Packet Level Load Balance inbound/outbound success with nth and route".


If you are not going to get a cooperative partner on the other side of the links, the loadbalancing described in nano is about the best you can do.

Please note that you absolutely need some of the other lines if you have incoming traffic. Traffic might come in through one but leave by the other interface with the wrong IP address otherwise. This is not always bad and often works if all links go over the same ISP. I have one cable and one dsl line from two different providers. I had a bit assymetric routing until I corrected it.
