I was previously using Ipchains to relay messages from my Linux machine to my Exchange server and vise-versa. Now I would like to use Iptables to accomplish the same function. I would like help inorder to accomplish this task.
Thinks to know. My linux machine has one Network card. Mial coming into my network would first go to the Linux machine and then relayed to my Exchange server which is on my inTRAnet. Mail going out with go to my exchange server and then to my Linux server and then out to the internet.
