Need help in creating Guest Access configuration on Cisco Aironet 1815

[allauddin86]

IP address is assigned to all Cisco AP 1815 through firewall. I want to create a Guest Wifi whom should not have any access to my internal network. I need help in creating it and what is all the requirement.

As always, there are multiple ways to achieve this. But as you already have a firewall in place, I would go for the following approach:

1. Configure an additional WLAN with an additional VLAN on the AP.
2. The VLAN terminates on the Firewall where you have the IP-interface and provide DHCP
3. The Firewall also controls the traffic from the Guest-VLAN to the other VLANs you have.
