DHCP & Windows Mobile 2005

[unaiur]

Hello

I've bought a WM2005 device and I'm having problems with DHCP. The device associates correctly with my WL500gx, but it can't retrieve a valid IP. In the logs, dnsmasq seems to be receving and answering the dhcp discover requests:

Mar 30 00:43:46 dnsmasq[108]: DHCPDISCOVER(br0) 00:09:2d:8e:a2:bb
Mar 30 00:43:46 dnsmasq[108]: DHCPOFFER(br0) 10.2.1.205 00:09:2d:8e:a2:bb
Mar 30 00:47:19 dnsmasq[108]: DHCPDISCOVER(br0) 00:09:2d:8e:a2:bb
Mar 30 00:47:19 dnsmasq[108]: DHCPOFFER(br0) 10.2.1.205 00:09:2d:8e:a2:bb
Mar 30 00:47:22 dnsmasq[108]: DHCPDISCOVER(br0) 00:09:2d:8e:a2:bb
Mar 30 00:47:22 dnsmasq[108]: DHCPOFFER(br0) 10.2.1.205 00:09:2d:8e:a2:bb

But no reply leaves WL500gx. I've verified that with airsnort. Running a tcpdump on the vlan0 interface, I can see the dhcp responses flowing through the wrong interface, but the router hangs up quickly so it can be a tcpdump bug. If I configure an static IP in the PDA, the wireless connection works perfectly.

I'm running the firmware 1.9.2.7-6b.

Can someone help me?

Thanks.
