Assigning IPs on a per-NAS basis?

["Jan Mulders" <lastchancehotel@gmail.com>]

Hello,

Trying to do a very simple task here - create a new check attribute
Pool-Name := servername, depending on what NAS sends the request to
the RADIUS server (identifiable by IP address or by name or whatever
in the request attributes).

What's the best way of doing this?

Thanks,

Jan
