    This port is the source address for the BootP service in DHCP clients requesting IP addresses from DHCP servers. If you have any clients configured to obtain an IP address automatically from a DHCP server they will send a packet called a DHCP discovery packet out on the network. This packet identifies that a client is searching for an IP address. The packet uses UDP port 68 as it's source address for the client, since it does not have an IP address that refers back to the client.

    Hope that helps.

    Both BOOTP and DHCP use the same reserved protocol ports for sending an
    receiving messages between servers and clients. Both BOOTP and DHC
    servers use UDP port 67 to listen for and receive client reques
    messages. BOOTP and DHCP clients typically reserve UDP port 68 fo
    accepting message replies from either a BOOTP server or DHCP server.

    Because DHCP and BOOTP messages use nearly identical format types an
    packet structures, and typically use the same well-known service ports
    BOOTP or DHCP relay agent programs usually treat BOOTP and DHC
    messages as essentially the same message type, without differentiatin
    between them.
