Unanswered Question
Oct 25th, 2007

I want to use ASA to be a DHCP Server for Wireless Client not it can't.

I check the debug log in WLC, I confirm the WLC have send the request to ASA.

In the ASA, it don't have any hits in the rule when the WLC send the DHCP relay request.

I have try don't use dhcp relay in WLC but don't success. Anybody have the same case with me? And Is the ASA can't support DHCP relay agent to request to get the IP Addr.

P.S. In the Network Design limitation so I can't use WLC to be DHCP Server.

Equipment:

ASA5510

WLC4402

How can I fix it.

Thank you very much

I have this problem too.

The issue is that the ASA doesn't accept DHCP requests from a relay agent, only broadcast DHCP requests. In the 4.2 version for the controllers there is now an option so you can change the way the controller forwards DHCP requests so that it is sent as a broadcast and not from a relay agent.

So exactly how did you fix this issue? I have a similiar issue.

Thanks

you can upgrade your WLC to Ver 4.2 or about, or using ASA to relay dhcp traffic to a dhcp server. the ASA is auto drop the dhcp relay agent packet, so only can use these type of ways to solve it.
