So am I,I do know that forwarding has to be enabled in the kernel.
I did get it to work with iptables DNAT,though its a bit cryptic.I depends on what you want to forward to what.
This is for redhat.

to turn it on--
# Enable packet forwarding
echo 1 > /proc/sys/net/ipv4/ip_forward


to check if its on---
cat /proc/sys/net/ipv4/ip_forward
