Hi, This is company mail ID, so it is not easy to change the Format of mail ID. Sorry for any inconvenience. I am attaching the setup diagram... (Setup-sha) Explanation: DHCP Server running on Linux machine 1 on 192.168.10.1 DHCP Relay started with Server IP as 192.168.10.1 and listening on ppp0. and eth1. Link 2 is PPPoE link. The client is expecting an IP in the range 192.168.40.X But the DHCP Offer packet from Server is reaching only upto PPPoE Client interface... Then I did a setup like placing another machine between the client machine and pppoe-client machine and started dhcprelay on that machine which listens on eth interface. as shown in the attachment (Setup-jo). This worked.. In effect when dhcp relay listened on ppp0 interface th OFFER Packet is not reaching Relay. But while dhcp relay is listening on eth0 interface the OFFER Packet is reaching client through relay. ipforwarding is enabled in all machines. Is there any other configuration I missed Rgds Joby -----Original Message----- From: Bill Unruh [mailto:unruh@xxxxxxxxxxxxxx] Sent: Tuesday, May 23, 2006 9:31 PM To: Joby Thampan Cc: 'linux-ppp@xxxxxxxxxxxxxxx'; 'dhcp-users@xxxxxxx' Subject: DHCP failure on machine with ppp running.

I do not knw what you mean in your description of the problem however. Your machine contains both a ppp and an eth0 interface? and you want it to set up dhcp on eth0? How do you go about it? Also please use subjects to your emails and do NOT use all capitals in your name. both are typical of spam and your email almost certainly got tossed out from almost everyone in this group as spam. > > But when I made DHCP Relay listening on ethernet interface on a > different machine other than the machine containing PPP Interface DHCP Offer > Successfully recieved. > > If somebody knows, Please explain why this is so??? > > Rgds > joby > > > --------------------------------------------------------------------------- > "This e-mail and any files transmitted with it are for the sole use > of the intended recipient(s) and may contain confidential and privileged > information.
