bonding of 2 dsl lines

skyliner

I want to bond 2 dsl lines:

I've got a root server on the internet and it was my first idea to create two tap-vpns to the server. after that I wanted to use the kernel-module "bonding". But I didn't get it working with balance-alb.

Adaptive Load Balancing - provides both transmit load balancing (TLB) and receive load balancing for IPv4 via ARP negotiation. Doesn’t require special switch support, but does require the ability to change the MAC address of a device while it is open.

My second idea is to use "Routing for multiple uplinks": http://lartc.org/howto/lartc.rpdb.multiple-links.html

I want to use a tun-vpn with redirect-gateway and udp to my host on the internet. I want to use 2 source-ips to connect to the vpn-server. Is that possible?

Do you have any other idea how to solve my problem?

Thank you!
