I have a Windows 2012 DNS server with an internal Forward Lookup Zone of internal.com (I'm not using my real domain names). I have a separate company.com domain hosted on an external DNS server. When staff want to access an internal host from the Internet (outside of the office), they use the url hostname.company.com. On my internal Windows DNS server I would like anyone trying to access hostname.company.com to be redirected to the appropriate internal host versus being sent to the public IP. I'm not familiar with how to configure this. I tried configuring another forward lookup zone for company.com on my internal Windows DNS server with an A record of hostname.company.com and the internal IP Address of the internal host. However, it did not work.
Any advice will be appreciated.
