On the controller you would normally associate an interface to a WLAN. While creating an interface that corresponds to the WLAN you have an option to specify DHCP server . Configure PIX as a DHCP server and see if this works.
I am having the same issue, just wondering if anyone has found a solution. I am trying to configure an Alcatel Wireless controller to use a PIX firewall. Wireless clients are not able to obtain an ip address via DHCP. The PIX reports:
DHCPD: DHCPDISCOVER received from client 0100.1302.5e8f.50 through relay 192.168.10.2
, packet discarded
Notice that the client Mac address is too long "01" is being added to the beginning. I have verifified that the Alcatel controller works when connected to a "Linksys" broadband router.
I would greatly appreciate any help you can offer.
To my understanding no Cisco firewall model will support acting as a DHCP server for hosts which DHCP messages are relayed by another device in between the client and the firewall. They would only be able to act as a DHCP server to a directly connected network or relay DHCP messages from a directly connected hosts to a server behind another interface of the same firewall.
