Does the gateway send RADIUS packets when people connect to it?

  If not, you can't use RADIUS to configure the behavior of the
gateway.

 

Im not quite sure what you mean, I know that:

1. The gateway has accounting "on" and every 3 minutes it updates the RADIUS with packets containing the sessions of connected users and any related data. (this might be a yes to your answer, but I am not quite sure)

2. The gateway checks with the RADIUS server if a user is allowed to use the internet and also how much time he is allowed to use.

3. I can see in the log file when people connect through the RADIUS and I can see updates in the detailed accounting log for an specific location.
