Traffic from WLC to Guest network

[ejdrijin1]

Hi,

I have a network were the controller is placed and a guest network. The guest network default gateway is an interface on the Cisco ASA. Even the other network default gateway is the ASA. I have an issue that from the guest network I can still access the controller.  

I have created access lists on the ASA to deny traffic from the controller to the guest network but still I can see the login page.

Also to make sure that there is not any other routes I shut down the Interface of the Guest network on the ASA the controller is not reachable. 

Any ideas why this is happening even when I blocked all traffic to the guest network? Or else is there a way which I can troubleshoot it or monitor traffic? 

Thanks.

Hello

Have you create the guest vlan on the switch and ssid/vlan on the wlc?

What security method and authentication have you used?
