For the remote sites, you should configure the AP's in H-REAP mode. This will allow you to define what SSID should be mapped to what local vlan. When an ap is in local mode, all traffic tunnels back to the wlc. In H-REAP mode, you can define what SSID you want to drop off locally and what SSIDs you want to tunnel back.
Thanks for the quick reply. Problem is we have only Aironet 1231G (about 25 or so total). I understand those are not supported for H-REAP.
What I tried as a workaround was to setup DHCP on the WLC. This works fine but I am concerned about performance - maybe I don't need to be. I have 5 remote locations, each would need three scopes. Should I proceed with DHCP on the WLC?
You can or else you can use your current dhcp. I don't like to use the wlc as a dhcp server. The interface that you create on the wlc needs to be local to the site the wlc is on. The issue you may have is that AP's in local mode might loose connectivity to the wlc an bounce which will cause issue with clients.
Just to add.... since all traffic will be tunneled back down to the wlc, make sure those subnets are large enough for all the devices that may join. Depending on your link between the sites, you may or may not have issues due to the fact the ap's have to run in local mode.
