client not able to getting the IP address from the DHCP serv

Hi Friends,

I configured DHCP server in linux machines.

When i connect two Linux machines directly, the server able to assign the IP address to the client. But when i connect the client through the router, the client not able to get the IP address.

All DHCP requests are coming from DHCP client to DHCP server. But DHCP server not able to Acknowledge to that clients.


Can any one tell me what might be the problem.
