  The clients.conf file defines IP, secret, "type", etc. for the NASes.

  The huntgroups file allows you to put clients into logical groups.

  So key off of the equipment type, not the IP.

  Not really.  The syntax of the huntgroups file is pretty limited.

  Yeah... that won't work.

  You can use "unlang", though:

	if ((NAS-IP-Address >= && \
	    (NAS-IP-Address <= {
		update reply {
			Idle-Timeout := 1800

  That's pretty straightforward.
