flush existing firewall and apply new rules.

#iptables -A INPUT -i eth0 -m state --state ESTABLISHED,RELATED -j ACCEPT
#iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
#iptables -A FORWARD -i eth1 -j ACCEPT

#iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 80 -j DNAT --to 192.168.0.100:3128
#iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3128

TRY by default DROP rules for INPUT and FORWARD;then accept the ports i.e try defining the rules one by one!

iptables -P INPUT DROP

iptables -P FORWARD DROP

Also see that DNS is configured properly!Configuring caching dns (with bind)will help you!
