There was a list of URL posted here in the debian-firewall mailing list.
One of them had a section that might be of interest. It has the balancing
for the opposite direction, but it should help get you there.
http://www.linuxsecurity.com/feature_stories/kernel-netfilter.html
The appropriate section:
So, to develop a simple and inexpensive load balanacing solution,
you might use the following to have your firewall redirect some of
the traffic to each of the web servers at 192.168.1.100, 192.168.1.101
and 192.168.1.102, as follows:
#
# Modify destination addresses to 192.168.1.100,
# 192.168.1.101, or 192.168.1.102
# iptables -t nat -A POSTROUTING -i eth1 -j DNAT \
--to 192.168.1.100-192.168.1.102

My thoughts on h4x0rs: Consider the complacency
and arrogance that would cause a porcupine to sleep
on its' back.
