We are trying to hit a client's web server by their internal name across a vpn. The name space they are insisting upon using is the same as their public namespace (ex: web1.abc.com). They are not going to publish this 'web1' record to their public DNS servers. I would normally use a dns rewrite or alias to have the public record returned as a private IP address so I can hit the 'web1' server across the vpn using the private IP's. But since they are not going to publish the name to the public DNS, how can I rewrite the response? It will come back as a non-existent host from the public DNS. The client isn't going to allow us to hit their internal DNS for name resolution nor will they allow us to create a secondary zone on our internal DNS servers.
Thanks in advance for any suggestions.
