It's posible to when a user disconnect from the directive Session-Timeout deny connect again in the following 30 Min?

You will need to track that information in a database. Remember: FreeRADIUS isn't a database, and doesn't store data. It doesn't store information about when a user logs in, when a user logs out, or when their session was timed out. That information is in a database. So... you need to configure FreeRADIUS to store that information in a database, and then to look it up again later. Alan DeKok.
