Which package is required for a PPPoE server on MikroTik RouterOS?

A PPPoE (Point-to-Point Protocol over Ethernet) server on MikroTik RouterOS specifically requires the PPP package to function. This package provides the necessary protocols and functionalities for establishing and managing PPP connections, including PPPoE.

The PPP package includes support for various PPP-related protocols and options essential for handling user authentication, session management, and IP address assignment, which are critical components of a PPPoE server. Without this package, the router would not be able to process PPPoE connections effectively, making it impossible for clients to connect through PPPoE to the network.

While the other packages mentioned may serve important roles in specific contexts within MikroTik RouterOS, they do not provide the functionality required for a PPPoE server. The user-manager package is used for user management and accounting, while the synchronous package pertains to synchronous connections that are unrelated to PPPoE. The system package provides the core operating system functions but does not include PPP-specific functionality. Thus, the use of the PPP package is essential for integrating and operating a PPPoE server on MikroTik devices.
