Open Guest Network and DHCP utilisation

For guests to be able to easily access our wireless network, the Layer 2 security is Open, with Web Authentication implemented at Layer 3.


The problem I have is with having no layer 2 security (open), is that my dhcp pool is utilised by devices that may never authenticate. It becomes more of a problem if the DHCP pool is associated with DMZ Public addresses...


Is there anyway of moving the client to a different DHCP pool after web authentication? (ie. from a Private pool to Public pool).


I can see from the documentation that Dynamic VLAN assignment is not possible with web authentication :(

Are you saying that the clients are getting public dhcp address? What you should do is setup DHCP on the WLC for the guest. You will have to create a guest vlan and a dynamic interface that is on that vlan. Then place that vlan on your DMZ that would NAT to one of your public ip address.
