We have an exchange server on our internal network. The MX record is pointed to a 2nd IP address on our T-1. I am trying to set up a translation rule to forward the mail to our interal exchange server.
Anyone know of a document that explains how to do this?
I guess what I'm trying to figure out first is how do I "grab" that other IP so when a packet goes to it NAT knows to forward it inside to exchange.
