I was configured that, but is in same vlan with my other SSID, i need to use only one subnet with 25 bits for guest SSID.
This is my configuration:
Vlan 10, 10.1.48.0 /22
DHCP(server AD), give 10.1.48.0/22
i want to access with guest users to 10.1.51.0/24
WLAN virtual-ap "VAP-Guest"
vlan 10
....
I hope this example was correct... and sorry for my english
