You can use iptables to configure the Linux box as a NAT router.

Yes, you can.

I actually provided two links to give you a good idea of what you're up against. The links are to the relevant pages of the RHEL 4.0 manual. Did you even look at them? The most basic iptables configuration to provide NAT to a LAN would go something like:
Code:
iptables -P FORWARD DROP
iptables -A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i $LAN_IFACE -o $WAN_IFACE -m state --state NEW -j ACCEPT
iptables -t nat -A POSTROUTING -o $WAN_IFACE -j MASQUERADE
To enable IP forwarding, you do a:
Code:
echo "1" > /proc/sys/net/ipv4/ip_forward
If you want a page that explains what NAT is, click here. For a good iptables tutorial, click here. The tutorial is relatively advanced, don't think that you need to master everything in it. But you definitely should have a good general understanding of what iptables is and how it works. Any other information you need to get this working is just a Google away. Or search through the forums here at LQ because these types of setups are covered quite often.

Asking for a step-by-step is a pretty tall order, you will have much better chances of getting help if you first read-up on this, then give it a shot, and then come-back with specific questions about any snags you hit along the way.

just disabling a firewall is not going to be sufficient. you need to follow the document that you have been linked to. you then also need to configure the windows machiens to use it correctly. if you can confirm which parts you have and have not done then we can easily look to work out if anything else is awry. you may benefit from describing what sort of access you actually want, principally routing (iptables) or proxying (squid)

for word documents, try openoffice.

reply( urgent please)

issue still persist...........

Let me explain you again.
I have 2 computers
Linux : has two Ethernet cards : eth0: IP provided by DHCP( through by ISP), eth1: Ip address : 192.0.0.1
Windows XP pro: IP address 192.0.0.2

Now I want to access Internet through windows. When I try to access get message from Internet Explorer " Connection refused".

And also please provide me that what all steps should I follow now to access Internet on my windows computer?

Thanx

Configure the Linux box to do NAT using the links and info above. Then configure the gateway address on the Windows box to be the IP of the LAN interface (eth1) on the Linux box. Set the Windows box's DNS servers to be the same as what the Linux box uses. That's pretty much it.

Please post the output of all these commands from the Linux box:
Code:
iptables -nvL
Code:
iptables -t nat -nvL
Code:
cat /proc/sys/net/ipv4/ip_forward
Code:
ifconfig
Code:
ping -c3 linuxquestions.org
Code:
ping -c3 192.0.0.2
Make sure the Windows box is turned-on when you run the last command. BTW, if you are concerned about having the WAN IP from the ifconfig command posted here please edit the last segment or two of it. For example, instead of 64.233.187.99, have it show 64.233.xxx.xxx. Also, please use code tags when you post these outputs.
