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
