I need to enable TLS between an exchange 2007 and exchange 2003 organization each having a single bridgehead server. I have the steps outlined by microsoft exchange team as follows:
The issue is that my exchange sits inside my network and I have a barracuda on a DMZ which forwards port 25 through my firewall. My outbound connector setup would be straight forward as it would simply pass-through the barracuda and forward to the other organization.
The article recommends setting up a second IP and using that dedicated IP for the traffic received from the remote exchange server. SInce I have a dedicated IP on the DMZ forwarding from the barracuda to the exchange I am not sure how to accomplish the inbound connector for the TLS connection. I do not see how I can assign a dedicated IP with this configuration.
