I am having problem with my 501 DHCP server. that PIX box responsible to
provide IP addresses for wireless clients via a wireless AP and a
controller.

dhcpd address 1.0.0.20-1.0.0.35 inside
dhcpd lease 3600
dhcpd ping_timeout 750
dhcpd auto_config outside
dhcpd enable inside

if I use a Windows DHCP server and add DHCP Vendor Classes option it would
work fine.

I couldnt find similar option for PIX, is there any?
is there anyway to do more troubleshoot? and get this to work?

Thanks for any help.
Rob

I have used ASA dhcp server option in conjunction with a WLAN
controller. Is the "inside" interface referenced in your
configuration in the same vlan as layer 2 dhcp requests will originate
from Wireless users, else the DHCP server will never see the request
for IP address. There are possiblities for forwarding these protocols
from one vlan to another using ip helper-address commands.

Any thought?

What are your WLAN security settings? I would start by looking at
logs on your wireless LAN controller and WLAN security settings and
your client PC wireless settings, perhaps you are not matched and you
are not getting an IP address for that reason.

Is your "inside" network intended to be wireless LAN only? Do you
have any regular wired lan infrastructure behind the PIX inside
interface?

I am not sure about your security objectives or the bigger network
picture here, but generally I would not recommend combining wireless
LAN clients and LAN clients in the same network user VLAN.

we dont have any security and no wireed LAN/computer connected to inside, it
is for public usage with no additional security.
