Cisco Wireless :: 2504 Client Unable To Get IP Address On Guest Wlan

I recently setup a 2504 WLC that has two primary WLANs (internal and guest) which get their IP addresses from a central DHCP server using the local router's broadcast forwarding.  Things seem to be working well for the internal wlan, but clients on the guest wlan don't seem to be getting IP addresses.  If I give the client a static IP they are able to communicate across the wlan okay.
 
It is worth noting that I am using LAG between the controller and router and this guest wlan is really just a regular wlan (with PSK) that has an access-list applied to force it to the internet only.  The access-list should be allowing dhcp requests through, but in any case, I removed the access-list and it made no difference.
 
Here is a debug client for a machine connected to the guest vlan (vlan 33).  The internal wlan is on the 10.10.10.0/24 network (same as wired and same that the AP's are connected to) and the guest wlan is 10.33.0.0/16. I don't understand why I am seeing the dhcp request come from the internal vlan/ wlan first and it gets an IP address on this network.  I then see a request on the guest wlan/vlan at which point it appears to get a valid IP address on the guest network (10.33.0.0), but the client never sees this.   [code]
