Forwarding using IPTables

depam · 01-17-2006, 07:40 PM

For instance, i have a machine with two NICs...eth0 with a static IP and eth1 with a local address.

I want the machine to forward requests of port 80 to a certain machine having an IP of 192.168.1.140. Is it possible? How will I do it using the IP tables?

How can I set ip up in such a way that it will serve as a firewall and router at the same time?

Thanks in advance.

Yes this is possible, and is described in the myriad of iptables tutorials spread over the net. Go ahead and read one or two

Here is the basic rule though, to get you started:

Code:

/sbin/iptables -t nat -A PREROUTING -p tcp --dport 80 -i eth0 -j DNAT --to 192.168.1.140:80
