Do this:
- Make sure your Centos has two network card. One connected to
internet, one to local lan. Make sure the Centos can already browsing internet. Example internet: eth0 192.168.1.1 local: eth1 192.168.2.1
- Activate ip forwarding in /etc/sysconfig/sysctl.conf
net.ipv4.ip_forward = 1
Run sysctl -r to reload the new setting
- Type this iptables command to share internet:
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
- Set your windows box to use 192.168.2.1 as it's default gateway.
Don't forget to give it DNS too like 8.8.8.8

Thank you very much for your help. At now, I have put my windows machine behind my centos 5.6 firewall server with just one NIC. The windows machine can ping 192.9.9.3 but it cannot browse Internet like connecting to google. I have set its DNS too. Can you please let me know what step is missing? Thank you
