I have a problem and need assistance. We have had 1 site for years. Our IP subnet is 172.16.1.x with a mask of 255.255.0.0
We are setting up a new site this week. The two sites will be the same domain and connected with a VPN. We will have a domain controller and file server plus some PCs at the 2nd site. I would like to keep the 2nd site on a separate subnet, but have some serious questions how to do that. Would like to use 172.16.2.x as the subnet. But here is my problem. I want devices on both subnets to be able to access devices on the other subnet. How do I even begin to set this up? Do I set up a second address range in my DHCP (running on Windows 2012 Server R12)? Do I change the network mask? How do I force devices at the second site to use the .2 subnet? How do I do this correctly? Need to do this very soon and just not sure what to do. Please advise. Thanks.
