DHCP protocol is designed for broadcast networks, not for PPP. It will not work on ppp interface. If you want your server to assing address to its clients, you should use LCP. To configure the latter read mpd docs.
Thanks for the reply - but I'm trying to do something a little bit advanced, that I thought some of you might have already known about...
Yes, I am having PPPoE/PPP assign the IP address to my client. The problem is that I need more - specifically vendor-specific configuration parameters, that can be obtained via DHCP. That's why I need to run DHCP over PPPoE.
My research indicates that rather than doing the usual DHCP DISCOVER to start things off, I should be able to send a DHCP INFORM message, which includes my already-assigned IP address. The DHCP server should see this, it then MUST NOT (according to the RFC) lookup the address in its lease database, but it then should respond, sending the all the configuration parameters *except* an IP address, back to the IP address that was included in the message.
Thus my desire to get dhcpd running with mpd pppoe... Any suggestions?
Thanks, Gary
