Sophos AP / Cisco Switch

Hello,
i have a problem with a DHCP service and a Sophos AP connected to a Cisco Switch.

Here my configuration:
I have two VLANs 1 (default  / internal) and 20 (guest)
DHCP service for VLAN 1 does an Windows 2008 R2 and
for VLAN 20 does the UTM DHCP service. With two different ip ranges.

The Ports for the UTM and the Accespoint are trunked.

UTM version is 9.315
Sohos AP 50
Cisco Catalyst C2960S-48LPS-L

So my problem...
If i connect to WLAN 1, which is bridged to VLAN 1 a don't get an IP address.
When i connect to the WLAN 20, which is bridged to VLAN 20 i get an one and everything works fine.

I tried already an other switch from HP and everything works. So i thing some configuration on my Cisco switch is wrong...

  • Scott, at one point, I watched the DHCP Live Log along with tcpdump -i eth0 port 67 or port 68 -e -n and the Live Log showed the same activity.

    Cheers - Bob
