I am considering expanding my small domainn to a dedicated server rental service. I am renting two dedicated to test setting up a domain. The problem with these rented servers is that they randomly setup the servers in a different subnets and I need to setup a way to connect them together so that they can become one domain. I would asume that I need to do this using a VPN. I believe the servers are in the same building and it should work ok if I can get them to connect.
What are the steps to get this done?
