Can Controller LAN and Wireless AP client are using different IP
Controller is not doing any L3 functionality, so It has to be something else. But in your scenario can you configure a firewall as Trunk Port (carrying multiple vlan traffic) connect back to WLC ? I doubted.
Best solution would be having a L3 switch in place of the controller in your topology diagram & connect WLC on to that switch via a trunk port. In this way all the VLAN gateway will be the L3 switch SVI
Re: Can Controller LAN and Wireless AP client are using differen
Like Rasika mentioned, you really need a switch in between. Before you start creating multiple subnets its always best to see how the wired side works and get that piece to work first. This way you understand the flow of traffic and it asks makes setting up the wireless easier. In all the Cisco docs you will see the WLC connected to a switch. This can be a layer 2 or layer 3 switch, but its always presumed that routing is working and you do have a device that does the routing. Trunking just allows the WLC to pass multiple vlan's to and from the switch. If you don't have a switch, then you need to have your FW do the routing and hopefully it supports trunking.
