Hello Mjnayak
I beliaeve you can
Go on the tabs you go up in your virtual controller go to more-> go to DHCP click on it
and you will see this
On local dhcp Scopes
In there click new and put the DHCP scope and all the information in there but you put a random vlan let say you put vlan 100
When you done go and create a new SSID
When you are in here
Put vlan network assign and put vlan 100 in there and i bealive it should work.
I do this to assign local ip address when im doing vpn termination from a instant ap to the Controller but it should work i bealive for this situation.
Try that
Cheers
Carlos
