iptables -vt nat -I PREROUTING -i eth0 -d 192.168.0.3 -p tcp \
    --dport 80 -j ACCEPT

*Might* do it. My guess is that this router is seeing the packets to 
192.168.0.3 for some reason. My rule (-I to insert at top) will bypass 
your REDIRECT rule.

Edmundo's question is valid. Normally a host would not go through your 
firewall to reach another host on the same physical segment. So my 
guess might be wrong.
