We are looking into netflow to monitor our DSL users usage. We have the problem the when the routers dial onto our LNS they are assigned a virtual access interface. If users reconnect they are assigned another one thereby leaving us with users spread accross many over the months.
I would like to know if anyone has ever found a way to either export the username/ip from the LNS or somehow set up a netflow program to pull the data in the right way.
I hope this makes some sort of sense!
