I need help with this DNS problem, and I hope I will make it understandable.
DNS forwards to
NAT forwards to
Goes to server:
If mailbox exists in another server, the first server will respond with the server’s FQDN, which is an internal domain name and is different from the external domain name.
Let’s say the client’s gets information saying that the server name is Exchange2.internal_domain_
The client attempts to communicate with this server and not succeed, because the name will not be resolve over the internet.
Now the question is:
Is there a way to make the first server reply to the client with the external domain name, which is domain_name.com, so the second exchange server will be exchange2.domain_name.com?
This domain resolves over the internet to 188.8.131.52
The third server resolves to 184.108.40.206.
This just a temporary setup so we can migrate all mailboxes and public folders to the second and third server, and then make the first one a front-end server.
All comments and suggestion are highly appreciated.
