19.6. RADIUS Control messages

The FireBrick also supports RADIUS control messages. These can be used to disconnect a connection, or to update the details of the connection including line speed, time or data limits, and routing (apart from the PPP endpoint and DNS).

The update can also include change of routing table. This can be useful to move an active connection in to a walled garden and back without ever dropping the PPP connection itself. This can be useful for credit control systems.
