It is normal for the PPP server to hand out this information - having
obtained it if necessary from the DHCP server.

Don't forget that the ISC server doesn't bind (IIRC) with a PPP
interface. It will work fine if the PPP server is on another machine
AND that other machine also correctly handles the packets correctly
(relaying if required - but the same limitation applies !).
