In WLAN, due to MAC association on Access Point (AP), I can't send the DHCPDISCOVER messages using random MAC addresses. But if I keep my original MAC address as the source ethernet MAC a and random MAC address in the CHADDR field of DHCP packet and send the DHCPDISCOVER message, it is passed by the AP and transmitted to the DHCP server on the wired side. But again, when the DHCP Server replies back with DHCPOFFER message, it extracts the CHADDR mac from DISCOVER message and make it as destination MAC address for DHCPOFFER message. When it reaches to AP, it directly drops that packet because that random MAC address is not associated to any device at all.. What to do, please help?
Note: Its working fine on the wired LAN.
