According to what you've written, you're not actually doing NAT, but you're simply port forwarding.
You're firewall isn't set up to properly do MASQ from what I'm surmising. You need to make sure that your firewall has: $IPTABLES -t nat -A POSTROUTING -o eth0 -j MASQUERADE near the top...not at the top, but after any flushing and clearing.
