Error in relay while using ISC DHCP code????

[ameen.shajahan at wipro.com]

Hi all ,
                I am using ISC DHCP-4.2.3 code and testing the DHCPV4 server and relay.

                Also I am using the default conf file.
                Client and server communication happened successfully by sending DHCP discover , offer ,Request ,Ack messages.

                But in relay there is some problem.

                SERVER IP address is 10.5.5.0
                RELAY IP address is 20.5.1.1
                I want to know whether I should use the same conf file or I should make some changes in it.

In Client side



C:\Documents and Settings\admin>ipconfig /renew

Windows IP Configuration

An error occurred while renewing interface Remote : unable to contact your DHCP
server. Request has timed out.

C:\Documents and Settings\admin>

I have attached the conf file. Please have a look.



My problem is how to run the relay using ISC DHCP
What should I change?
Where would be the problem actually??

Regards,
Ameen S
