Ensuring data is transferred over internal network
What do I need to do to ensure that communication between two servers is happening in this way? Presumably I must connect to Server B using its Private/LAN Network IP (after adding one in the control panel) - but is this all that is required? (I don't know if I must do anything on server A to make sure that requests to server B in this way are routed over the Private/LAN Network).
Linux Static IP Configuration
Once the server has been rebooted with the new network configuration, you're all set!
