Load Balancing

[NiY]

Greetings! I have yet to find a definitive answer on this subject, so
I was hoping someone would let me know the official way to go about
this, or if it's even possible.

We have two ADSL services coming into out building. We would like to
use them both on one network, using a multi-homed FreeBSD box, if
possible. So the scenario would like this.


ADSL1----\                                                             / -- Host
               Freebsd Load Balancer / NATD ---- Switch --  Host
ADSL2----/                                                            \ --Host

Can it be done?
