Manny, I just replied to the same question on this list. The reply is
below.

Vortex,

If you're referring to network load-balancing, say for example using two
different interfaces or links on the same machine, then I've done it for
some of my clients using Multipath Routing and Anastasov's kernel
patches. Basically, it's like configuring two default gateways on the
NAT'ing machine using weight metrics for balancing. 

As for incoming connections, I had to settle with round-robin DNS, since
EQL and/or "Bonding" needs to be done on both ends.

Basically, I had to repatch my kernel for the advanced routing features.
Use iproute to generate the new default gw entries/tables (this will be
the different default gateways of your multiple links), and then
configure it to balance between the new gateway tables using weight
metrics. 

eg: weight 10 for the 384k DSL link, then weight 5 for the 256K DSL
link.

All commands are done using ip route.
