I am not too sure this is the correct term but what I need is to get the external address 1.2.3.4 port 25 to go inside to 10.1.1.4 port 26. I have a spam filter that listens to a port and sends to exchange on a different port; the problem is that I cannot move exchange listeners from port 25 because of intersite communications - via VPN
How can I do this port translation?
Thanks
