Have you looked OpenBSD with pf? You can create rules that map outbound
session to a different DSL router, interface, and/or gateway based on
any number of rules. The man page pf.conf[1] and more precisely the
"ROUTING" and "POOL OPTIONS" section will allow you to create very
dynamic rules to define how to handle all outbound routing load sharing.
NATing also comes along for the ride.=20
A basic example is in their FAQ[2].
This type of setup is not the most common so a straight up HOWTO is most
likely not going to be found. Sorry I am not able to give a more direct
and Linux based answer.=20
