Executive Overview:

Complete technical guide to automated MikroTik PPPoE client disconnects on billing expiration date using API and RADIUS integration.

The Bottleneck of Manual Expiration Management

Manual disconnection through Winbox consumes valuable engineering hours and leads to human error. Automated cutoff enforces strict payment discipline across your subscriber base.

Technical Architecture

fiberNox communicates with MikroTik RouterOS over encrypted TLS API or FreeRADIUS CoA. When an account expires, the active session is disconnected, and the user profile is changed to a restricted walled-garden pool.
