Thank you all for your reply!
Do you mean that I cannot start the dhcpd as "./dhcpd
-cf /var/etc/dhcpd.conf ppp0"? And have to do the dhcp
relay as "./dhcrelay -i ppp0"? Could you please give
me a example? (sorry, a little confused!)

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

AND that other machine also correctly handles the
(relaying if required - but the same limitation
