1. PublicIPServer: Ubuntu Server 16.04 with public IP address and all incoming ports blocked except SSH. OpenVPN Access Server installed with trial 2-user license.
2. LANServer: LANServer connects to PublicIP using OpenVPN Connect. Some port (e.g., 443) on this client provides services.
3. WANClient: WANClient connects to PublicIP on some alternate port (e.g., 1443) and must be able to access service on LANClient
The task is to document the correct configuration of the PublicIPServer fully.
