Our domain is hosted at rackspace and we use there DNS manager for managing DNS entries to all of our public servers.
We have entries for things like WebServer.MyDomain.com, AppServer.MyDomain.com, etc. All those machines have public static IP addresses.
We have a number of machines at our main office that we need access to remotely that are behind a firewall and we only have 1 static IP address.
I want to setup dns entries on a server at the office so that MyPC.MyDomain.com will get routed to my desktop pc behind the firewall.
I'm running Windows Server 2008 and have DNS installed. Here's what I think I need to do:
- Setup an alias on rackspace that points MyPC.MyDomain.com to the server at the office.
- On the office server setup dns and create a new Forward Lookup Zone MyDomain.com
- Create a new A record in the new zone on the office server that points MyPc.MyDomain.com to the internal IP address.
- Setup the router to point to the new internal dns server
Is this correct? Am I missing anything?
