Final answer:
macOS Server provides network and VPN services, including file sharing and secure remote access, with support for L2TP over IPSec and configurable access control lists for users.
Step-by-step explanation:
The Apple macOS Server provides various network and virtual private network (VPN) services for users and organizations seeking to manage Apple devices and their network interactions more effectively. The server offers features such as file sharing, calendar sharing, profile management, and Time Machine backups over the network.
For secure remote access, it supports VPN protocols including L2TP over IPSec and can be used to allow secure connections for remote users to access internal networks.
The VPN service can be easily configured via the Server application, allowing for the management of user access levels, encryption preferences, and network routing choices. The VPN supports access control lists (ACLs), which define who can connect, and with what permissions, ensuring secure and controlled access to the organization's resources.
