I have been trying to configure a guest network for my Cisco Catalyst 9800-L Wireless Controller for some days now. For the guest network, i want it to use an internal dhcp on the controller. I have been trying for days now, however, when a client connects to guest WIFI network it does not receive a DHCP IP address. POOL: ip dhcp pool localpool network default-router dns-server lease infinite enter image description here

SVI of vlan 10 was created for DHCP pool interface Vlan10 description VLAN 10 ip address pool localpool ip helper-address no autostate enter image description here Management is on : GigabitEthernet0 and TwoGigabitEthernet0/0/3 will provide internet connectivity for guest network - gateway is enter image description here

Guest network policy snaps:

Hoping to get some help. First time I am configuring a CISCO WLC 9800. I got the internal network wlan to work to radius server on Windows NPS but this guest network using internal dhcp pool is a pain.

Regards, Thanks in advance.

Your pool is misconfigured. The default gateway will be the router interface on VLAN 10 and must be in the same subnet as the pool.
