[CentOS] ls network address traslation different in centos?

Hi all

ls the network address traslation in centos5.2 different?

I disable the default iptable rule and use the following commands but I can't connect http://public:8080 from outside to this host 192.168.0.10 port 80

eth1 is public address eth0 is private address 192.168.0.1

iptables -F -t nat iptables --table nat --append POSTROUTING --out-interface eth1 -j MASQUERADE iptables --append FORWARD --in-interface eth0 -j ACCEPT iptables -t nat -A PREROUTING -p tcp --dport 8080 -i eth1 -j DNAT --to 192.168.0.10:80

Thank you
