Radius itself will send attributes to the NAS. Depending on NAS type,
the Ascend-Data-Filter attribute will permit you to set up filters in
the NAS to limit the dialup users to specific destination IP addresses
and ports.

Don't think so. You'd be programming the NAS, which would have to
understand addresses, not services.

You can specify the timeouts. If you're working with your own NAS,
you'll find the attribute information for your NAS in the documentation.
If you're interfacing to a dialup wholesaler, ask them for details on
what attributes should be used for the NAS boxes they use.
