I'm not sure how far you've gotten ...  This is a good treatise 
on the subject (some if it is outdated for newer desktop 
distros)

Most of the key for what you are wondering about is in

iptables  -t nat -F
iptables  -t nat -A POSTROUTING -j SNAT -o eth0 --to MY_IP
echo 1 > /proc/sys/net/ipv4/ip_forward
