Can MikroTik PPPoE Server be used with a router between the customer and the server?

The MikroTik PPPoE (Point-to-Point Protocol over Ethernet) Server can indeed operate with a router positioned between the customer and the server. In this configuration, the router serves as an intermediary that handles the PPPoE communication, allowing clients to connect to the MikroTik server while managing traffic and authentication processes. This is useful in scenarios where network segmentation, additional security, or routing capabilities are essential.

The router can encapsulate the PPPoE sessions initiated by the customer, forwarding them to the MikroTik server. Furthermore, it can manage multiple clients efficiently, enabling a centralized point for configuration and monitoring of sessions. This architecture is widely adopted in various network environments, particularly in ISPs and enterprise networks, where scalability and performance are critical.

In contrast, having a direct connection without any intermediary might limit certain routing capabilities or create complications in large-scale deployments. Thus, it is perfectly viable and often advantageous to implement a router in between the customer and the MikroTik PPPoE server.
