You are trying to get to the Internet from other computers on the same subnet as eth1? They probably don't have correct addresses for the DNS servers. Are you configuring those computers manually or from DHCP? Or do I misunderstand your situation?

yes you are right

other computers are manually configured as eth1
and gateway is the ip of eth1.

But how can I set DNS of those computer? Because I get that DNS from dhcp via eth0. Should I set those DNS to that computers?

Boss, You are awesome. DNS was the main problem. I was trying for last several hours. Thanks again.
