    Hello,

     

    We have got many problems with some wireless clients (Windows Phone 7.5) who steal the network gateway.
    We use 4 controllers  ( 1 master and 3 local )
    They  are in version 6.1.2.8
    The controller are not the default gateway for wireless clients and the default gateway is behind the controller.

    Some features are activated :
    - Deny Inter User Bridging
    - Deny Inter User Traffic

     

    On clients' interface vlan:
    - bcmc-optimization

    On vap :

    - Drop Broadcast and Multicast
    - Convert Broadcast ARP requests to unicast

    Is there a way to block these clients?

     

    Thank you in advance for your advice.

     Emmanuel

    Seems you're not alone in this:

    Might that you can block them by adding "Enforce DHCP" to the AAA profile, and of course make sure the gateway IP isn't part of the dhcp scope.

    Thank you for your response.

    It works very well  !!

     

    I have found an anotther solution with validuser acl if DHCP is not used :
