problem made me tired

[aae900]

Hello guys,
I'm a new user of Linux (RedHat 5). So, please help me to fix my problem:

I have 2 different networks:
the first one is gateway machine (eth0), and the second is a private machine (eth1). So, I've configured the iptables and forwarding stuff and when I try to ping google.com on the gateway machine, it works, while it doesn't work on the private network. Note: I am using VmWare 7. I need your quick assistance about this issue.

I could say that the problem in DNS:

because when I use this command in the private network machine:
nslookup google.com , it says connection timed out; no servers could be reached

while in the public one, it works properly.....


who knows how can I fix this problem.
