Actually, that's something I would also like to know how to do best. We
have a similar situation here, but instead of MAC addresses we would
need to record the NAS-Port-Id sent by the NAS. The NAS is the access
controller for ADSL from a large telecomm here in São Paulo.

Does somebody have a good sugestion on how to record such an info (MAC
in Jurgen's case, NAS-Port-Id in my case) at the first access, and
verify it in the following times?

Thank you,

Marcos Roberto Greiner
