Or...and you may or may not like this idea....
You can write a script to build an arp table from the router via SNMP
(atTable in MIB-2) and use that table to configure your DHCP server.
The best SNMP tool I know of for scripting is Scotty but you'll need to
know Tcl since Scotty is really just an SNMP extension to the Tcl
language.
Feel free to contact me for more details.
Cheers,
Matthew
