ZD1100 - DHCP Relay doesn't give an IP

Hi everybody.

In my configuration i've a problem on a zone director 1100 with 12 AP - zf7372,

The setup is :

Vlans :

Vlan 20 - Corporate Vlan - DHCP server is in this Vlan
Vlan 590 - Guest Vlan
Vlan 600 - Mobile Phone Vlan
Vlan 700 - Management Vlan

All my VLANs are routed by a cluster of Barracuda NG Firewall.

For the network link of the ZD, the VLAN 20, 590, 600, 700 are tagged. The management interface of the ZD is tagged into the Vlan 700.

The AP are tagged into the Vlan 20, 590, 600, 700.

All this configuration is good.

The Vlan 20 - Corporate is Vlan authenticated by a server Radius into this Vlan.
The clients get their IP from the internal DHCP.

Into this DHCP, i've created some scope for the Guest Wlan and Mobile Phone Wlan.

On both of this Wlan the usage of a DHCP relay is enabled like this :

1) Create a DHCP relay with the IP from the Corporate DHCP server
2) On the Wlan enable the tunnel mode and select the DHCP relay in the select box.

When a client connects on the mobile Wlan for example, it doesn't get an IP address. If i configure manually the IP setting in the mobile phone for example, it has internet access.

In my firewall, the ports are open from the ZD in the management LAN to the DHCP server in the Corporate Lan on the DHCP Client Port - UDP 67.

Someone can help me please ?

Hey Nicolas, have you managed to resolve the problem?
I am currently struggling with something like this myself.
