    Hallo,

    this is my firt post on this community.
    I have a problem with a WM3600 system (2 in cluster) and access-point AP4620 when a device roaming from an AP to another. The client in dhcp mode acquire the correct IP when associated to the first AP and all ok; when the device roam to another AP, the client info report an IP 0.0.0.0

    This is the syslog report of the roaming problem :
    AP1 - AP1 %DOT11-6-CLIENT_ASSOCIATED: Client '90-68-C3-49-F0-BC' associated to wlan 'POLI_SMART' ssid 'POLI_SMART' on radio 'AP1:R1'
    AP1 - AP1 %DOT11-6-CLIENT_INFO: Client '90-68-C3-49-F0-BC' IP address '192.168.104.2', bssid '00-04-96-6C-52-D2' of radio 'AP1:R1' signal-strength -69dBm
    AP1 - AP1 %DOT11-6-CLIENT_DISASSOCIATED: Client '90-68-C3-49-F0-BC' disassociated from wlan 'POLI_SMART' radio 'AP1:R1': roam detected (reason code:8)
    AP2 - AP2 %DOT11-6-CLIENT_ASSOCIATED: Client '90-68-C3-49-F0-BC' associated to wlan 'POLI_SMART' ssid 'POLI_SMART' on radio 'AP2:R1'
    AP2 - AP2 %DOT11-6-CLIENT_INFO: Client '90-68-C3-49-F0-BC' IP address '0.0.0.0', bssid '00-04-96-90-B2-B1' of radio 'AP2:R1' signal-strength -47dBm

    Hello Nicola,

    Where is the DHCP server running and which activation criteria is configured? Is that SSID tunneled or locally bridged?

    Hello Grossi,

    Please try to change the SSID's bridging mode into local and check the status.

    Hope this will help.

    Add some info

    In this condition the Wireless Firewall Policy drop all traffic, but if i disable the policy the traffic is ok.

    The SSID is tunneled
    The wlan is a wpa2 pks
    The DHCP in a win2012 server (dhcp replay)
    There is a radius for the mac-address authentication

    Thanks for the suggestion but it is not possible; only the wm controller is connected to the other LAN services (RADIUS, DHCP, DNS, etc.); the access point is connected (vlan) to the controller only.
