Question Port Forwarding to RHEL Internal Webserver

Hi there,

I've got an internal web server hosted (box B) that has a web application running. And there's another external web server (box A) that has an external IP to it. I want the 'box B' to be made available externally through 'box A'. Now, how am I supposed to do the port forwarding? All I want is the http requests sent to 'box A' on port 81 should be forwarded to 'box B' on port 80. At the same time, the web applications running on 'box A' should not be disturbed. Both the servers are running RHEL 4. Kindly help.

DNAT is what you need to do for that. Check it out here. http://iptables-tutorial.frozentux.n...tml#DNATTARGET
Also the port 81 needs to be opened to the outside on box A.
