I've got the following:
Say I've got an MP3 server (192.168.2.10).
I want the users to log in via CoovaChilli, but traffic to this server must not be calculated in their usage.
Traffic to other hosts EG the Internet must be calculated.
The host 192.168.2.10 should not be visible for users are not logged in.
Can this be done, where certain destination addresses's data usage are not tracked and reported upon.
