CNR Replacement

[Jon Otterholm]

Hi.

I am searching for a BSD-based CNR replacement. CNR (Cisco Network 
Registrar) is basicly a DHCP server that puts IF-routes on a router when 
a client has leased an IP-address. When the lease expires the IF-route 
is removed from the router.

This functionality together with IP-less VLAN-IF's and a local loopback 
IF (client gateway) offers a solution where you maximize IP usage and 
also getting a tracelog.

Has anyone out there built a similar solution on FreeBSD? I would very 
much like to replace my SiliconValey based proprietary solution with one 
based on FreeBSD. What are my chances?
