Hi everyone...

OK.. I'm new to Airespace so the way I'm thinking about doing this might be
silly.. But here's the setup I can't get working:

Currently our wireless access is stand-alone IOS AP's with a broadcast SSID
that goes to a VLAN that terminates in CCA.  CCA is providing DHCP and
authentication for all wireless. It hands out /30 RFC1928 space to clients.

We have purchased a 4404 AP controller and some of the little LWAPP 1000
series AP's and will eventually convert our 1130's and 1200's to LWAPP once
I get this all working.

I want the wireless to function 99% of the way that it does now but just
throw the controller in the middle for managemt of the Aps.  I'd prefer the
DHCP and authentication continue to be handled by CCA.  I've trunked the
wireless VLAn (601 in this case) and the Management VLAN to a port on the
4404.  I have LWAPP AP's successfully talking to it Via layer 2 and 3 and
I'm in the web GUI and all that fun stuff.

I created a dynamic interface on the 4404 that is in VLAN 601 and assigned
it to physical port 1.  It wont let me create that interface without
specifying an IP on it.  It seems that if I specify an IP on that it then
uses that as a relay address and sends the DHCp request from a client onto
CCA which then says "well I don't know about that network o I'm not giving
you an IP."  I really wanted the 4404 to just pass the request along at a
Layer 2 level and have CCA give back the IP and it would from there be just
like any other CCA user.

Perhaps my above explanation makes sense.. Perhaps not.. But if there are
any suggestion someone has I'd appreciate it. I read the "integrating
Wireless Controllers and CCA" doc on the Cisco site but it doesn't seem to
take into account using CCA for DHCP.
