We are currently running Exchange Server 2007 behind a firewall through which all traffic on our domain passes. The most common connection to our server is with Outlook 2007 while an end user is on the domain. We do have a few users who use Outlook 2007 while away from the network. They use an https://
connection to do so.
We are about to add another company to our email server: I've create an Accepted (Authoritative) domain since its name is different from our original domain.
All of that seems to be okay.
The end users for this new domain are out of our own state, so their connectivity must be done via the internet. The new domain is hosted by godaddy.com and a new "A" record is now pointing to the Public IP address of our firewall. I'm assuming the new firewall will pass the traffic correctly to the Exchange Server, since it's doing this now with our original domain.
My question is this: When I'm setting up Outlook 2007 on the end users' pc's, and get prompted for the name of the Exchange Server, what do I use? These new users will not be able to put in the NetBios name of our server because it's behind the firewall and has a private IP address.
