This is not a radius issue / feature. Your network devices will have to
be able to differentiate local versus internet traffic for you. If they
can, they *may* be able to just put the internet counter values in
radius accounting packets, but I don't know of any NAS that does.
Radius accounting packets just contain a single one-dimensional list of
packets/bytes in/out. What your NAS puts in them is a NAS issue.
If you're assigning fixed IPs, you might look at netflow. Packets like
"ipfm" and similar can be used to monitor traffic by IP from a port
mirror. All depends on your network architecture.
