Does the DHCP relay agent modify DHCP packets or the IP header? If so, what are the modifications?
What will be an ideal response?
The DHCP relay server modifies the DHCP relay agent field while putting the request from the DHCP client’s subnet to the destination subnet. The DHCP relay server frames the DHCP packets coming from the client such that the source destination is his own and the destination is the address of the server.
The reverse process is applied to the packets coming from the server and destined for the client. This is evident from the following trace:
